12x - 6 = 9x

Subtract 9x from both sides.

3x -6 = 0

3x = 6

I assume you can carry on from there.

12x-6=9x

first step: subtract x-variables to one-side of the equation

-6=-3x

second step: divide -3 to the other side to get the value of x

x=2 (final answer)

Lastly, you can check your answer of x=2 by plugging it into the original equation to see if both sides of the equation are equal.

12(2)-6=9(2)

18=18

Therefore x=2 is correct
