Simplify the equation by combining like terms:

7x²+ 4x - x²

Solve:

7x²+ 4x - x²

7x² and -x² are like terms, so combine them.

6x² + 4x

There are no more like terms, so your answer would be: 6x² + 4x

Answer:

6x² + 4x

12x>9 (2x-3)-15 solve for x and show steps please.
Verdich [7]

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
