Answer 3

To solve the inequality, we need to isolate the variable "x" in the middle expression. Here's the step-by-step process:

Given inequality: -2 < 8 + x/7 < 4

Step 1: Subtract 8 from all parts of the inequality to get rid of the constant term on the right side: -2 - 8 < 8 + x/7 - 8 < 4 - 8

Simplify: -10 < x/7 < -4

Step 2: Now, to isolate "x," multiply all parts of the inequality by 7 (since x is divided by 7): -10 * 7 < x < -4 * 7

Simplify: -70 < x < -28

So the solution to the inequality is: -70 < x < -28
