Question

Solve for x: 4 x minus 12 equals 8 x plus 24

Answer 1

x=-9

Explanation:

4x-12=8x+24

First you subtract 4x from both sides because you need to isolate the variable. You now have

-12=4x+24

Subtract 24 from both sides to have 4x all by itself. You now have

-36=4x

Divide by 4 and you get

-9=x
