Explanation:

First distrubite factors. ( 9(2x-3) = 18x-27)

Combine like terms. (-27-15)

2) 12x>18x-42

Subtract 18x from both sides.

3) -6x>-42

Isolate the variable. (divide -6 on each side)

Flip the sign since your dividing.

5) x<7

Answer: x<7

Explanation:

Given

Distributive property

12x>18x-27-15

Combine like terms

12x>18x-42

-6x / -6 < -42 / -6

x<7
