See the entire solution process below:

Explanation:

Step 1) Add color(red)(3)3 to each segment of the system of inequalities to isolate the xx term while keeping the system in balance:

-8 + color(red)(3) <= 8x - 3 + color(red)(3) < 2 + color(red)(3)8+38x3+3<2+3

-5 <= 8x - 0 < 558x0<5

-5 <= 8x < 558x<5

Step 2) Divide each segment of the system of inequalities by color(red)(8)8 to solve for xx while keeping the system in balance:

-5/color(red)(8) <= (8x)/color(red)(8) < 5/color(red)(8)588x8<58

-5/8 <= (color(red)(cancel(color(black)(8)))x)/cancel(color(red)(8)) < 5/8

-5/8 <= x < 5/8
