First step is to distribute 9 over 2x-3

12x>18x-27-15

Next is to subtract 18x from both sides of the equation

-6x>-27-15

Next is to subtract 15 from -27

-6x>-42

Finally just divide -42/-6

x>7

x has to be greater than 7 to satisfy this equation

12x > 9(2x-3)-15

distribute the 9

12x > 18x-27 -15

combine like terms on the right side

12x > 18x-42

subtract 18x from both sides

-6x > -42

divide both sides by -6

x = -42 / -6 = 7

x >7
