To find the value of x you need to get x by itself. First you need to subtract 5x from both sides. You will end up with -x=-12. Then you need to divide both sides by -1 to get x by itself. You get x=12

4x=5x-12

-5x  -5x

-x=-12

÷-1   ÷-1

x=12

Solution:

4x=5x−12

Subtract 5x from both sides.

4x− 5x = 5x − 12 − 5x

−x = −12

Divide both sides by -1.

−x/1 = −12/1

x = 12

Final Answer:

x = 12
