Math Problem Statement

Solve - 8 ≤ 5 x - 3 < 7

Solution

We are given the compound inequality:

85x3<7-8 \leq 5x - 3 < 7

Let's solve it step by step.

Step 1: Add 3 to all parts of the inequality

To eliminate the constant 3-3 on the middle term, we add 3 to each part of the inequality.

8+35x3+3<7+3-8 + 3 \leq 5x - 3 + 3 < 7 + 3

This simplifies to:

55x<10-5 \leq 5x < 10

Step 2: Divide by 5

To isolate xx, we now divide all parts of the inequality by 5.

555x5<105\frac{-5}{5} \leq \frac{5x}{5} < \frac{10}{5}

This simplifies to:

1x<2-1 \leq x < 2

Final Answer:

The solution is:

x[1,2)x \in [-1, 2)

This means xx is greater than or equal to 1-1 and strictly less than 2.
