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
