solve the equation. 8x+9(4x+3)-80=2x-3(21-4x)

Answer 1

Opening parentheses on the left and right sides separately:

8x + 36x + 27 - 80 = 2x - 63 + 12x

Simplifying left and right sides separately:

44x - 53 = 14x - 63

Subtracting 14x and adding 53 to both sides:

30x = -10

Dividing both sides by 30 and getting the final answer:

x = -1/3

Answer 2

Distribute the 9 and the -3

Collect like terms

Convert so all x are on one side and numbers on the other

Isolate x
