Answer:
a. x > 9
Step-by-step explanation:
7 - 2/3x < x - 8
Add 2/3 x to each side
7 - 2/3x+ 2/3 x < x+ 2/3 x - 8
7 < x + 2/3 x -8
Add 8 to each side
7+8 < x + 2/3 x -8+8
15 < x + 2/3 x
Get a common denominator for x of 3
15 < 3/3 x + 2/3 x
15 < 5/3 x
Multiply by 3/5 to isolate x
3/5 * 15 < 5/3x * 3/5
9 < x
