5x+8=9x+12 helpppppp

Marina CMI [18]

Hi there! :)

Answer:

$\boxed{X=-1}$

*THE ANSWER MUST HAVE A NEGATIVE SIGN!*

Step-by-step explanation:

First, you subtract by 8 from both sides of an equation.

5x+8-8=9x+12-8

Subtract.

12-8=4

5x=9x+4

Then, you subtract by 9x from both sides of an equation.

5x-9x=9x+4-9x

Simplify by equation.

-4x=-4

Divide by -4 from both sides of an equation.

-4x/-4=-4/-4

Divide by the numbers from left/right.

-4/-4=-1

$\boxed{X=-1}$ , is the FINAL/CORRECT ANSWER! :)

Have a nice day! :)
