Solve The Following Inequality 38 4x 3 7 3x

Solve the Following Inequality: 38 ≤ 4x - 3 ≤ 7 - 3x

When faced with a compound inequality like 38 ≤ 4x - 3 ≤ 7 - 3x, the goal is to find all values of x that satisfy both parts of the inequality simultaneously. This type of problem requires careful algebraic manipulation and a clear understanding of how inequalities behave under operations like addition, subtraction, multiplication, or division. Let’s break down the process step by step to solve this specific inequality and explore the reasoning behind each move.

Understanding Compound Inequalities

A compound inequality combines two or more inequalities into a single statement. In this case, 38 ≤ 4x - 3 ≤ 7 - 3x is a compound inequality with two parts:

1. 38 ≤ 4x - 3
2. 4x - 3 ≤ 7 - 3x

To solve it, we must find the values of x that satisfy both conditions at the same time. This means we need to solve each inequality separately and then determine the intersection of their solution sets.

Step 1: Solve the First Inequality (38 ≤ 4x - 3)

Let’s start with the left part of the compound inequality:
38 ≤ 4x - 3

To isolate x, we perform the following steps:

1. Add 3 to both sides to eliminate the constant term on the right:
   $ 38 + 3 \leq 4x - 3 + 3
   $
   Simplifying this gives:
   $ 41 \leq 4x
   $

2. Divide both sides by 4 to solve for x:
   $ \frac{41}{4} \leq x
   $
   This simplifies to:
   $ 10.25 \leq x
   $

So, the solution to the first inequality is x ≥ 10.25.

Step 2: Solve the Second Inequality (4x - 3 ≤ 7 - 3x)

Now, let’s tackle the right part of the compound inequality:
4x - 3 ≤ 7 - 3x

Again, we’ll isolate x step by step:

1. Add 3x to both sides to move all x-terms to the left:
   $ 4x + 3

4x - 3 ≤ 7 - 3x
$ 4x + 3x - 3 ≤ 7
$ $ 7x - 3 ≤ 7
$

2. Add 3 to both sides to eliminate the constant term on the left:
   $ 7x - 3 + 3 ≤ 7 + 3
   $ $ 7x ≤ 10
   $

3. Divide both sides by 7 to solve for x:
   $ x ≤ \frac{10}{7}
   $ This simplifies to:
   $ x ≤ 1.42857...
   $

So, the solution to the second inequality is x ≤ 10/7, or approximately x ≤ 1.43.

Step 3: Find the Intersection of the Solution Sets

We have two separate solutions: x ≥ 10.25 and x ≤ 10/7. To find the values of x that satisfy both inequalities simultaneously, we need to find the overlapping region of these solution sets.

The solution to the compound inequality 38 ≤ 4x - 3 ≤ 7 - 3x is the set of all x values that satisfy x ≥ 10.25 and x ≤ 10/7. Since 10.25 is greater than 10/7, there is no overlap between these two solution sets. Therefore, there are no values of x that satisfy both inequalities at the same time.

Conclusion

The inequality 38 ≤ 4x - 3 ≤ 7 - 3x has no solution. This is because the two inequalities have no common solution. The range of values that satisfy the compound inequality is empty. This can be determined by analyzing the individual inequalities and observing that the solution to the first inequality is a much larger range of values than the solution to the second inequality. The intersection of these two solution sets is empty, indicating that there are no x values that meet both conditions simultaneously.

The compound inequality 38 ≤ 4x - 3 ≤ 7 - 3x presents an interesting case where we must solve two inequalities simultaneously and find their intersection. After solving each part separately, we discovered that the first inequality yields x ≥ 10.25 while the second gives x ≤ 10/7 (approximately 1.43). Since 10.25 is greater than 1.43, these solution sets do not overlap at all. This means there are no values of x that can satisfy both conditions simultaneously. The compound inequality therefore has no solution, which can be verified by testing any value of x - you'll find that it's impossible for 4x - 3 to be both greater than or equal to 38 and less than or equal to 7 - 3x at the same time. This type of result, while perhaps initially surprising, demonstrates how compound inequalities can sometimes have empty solution sets when the individual inequalities point in opposite directions with no overlapping region.

The individual inequalities provide distinct and mutually exclusive solution sets, demonstrating the importance of carefully analyzing the relationship between the inequalities when dealing with compound inequalities. This outcome highlights a crucial aspect of solving inequalities: understanding the range of values that satisfy each individual condition and recognizing when their intersection is empty.

When that intersection is empty, the overall compound inequality is considered to have no solution, a concept vital for accurate problem-solving and a deeper understanding of the behavior of inequalities.
