Answer: -16

Explanation:

2x+5+7x = 8x-11 simplifies into 9x+5 = 8x -11.

Move 8x to the other side - put like terms together : 9x-8x+5 = -11

Which is simplified into x+5 = -11

Move 5 to the other side to isolate x: x = -11 -5

Combine -11 and -5

x = -16

Answer:

x

Explanation:

2x + 5 + 7x = 8x -11 Combine like terms

9x + 5 = 8x -11 Subtract 8x from both sides of the equation

x + 5 = -11 Subtract 5 from both sides of the equation.

x= -16
