12x6=9x

12x6=9x
12x  9x = 6
3x = 6
x = ? 
12x  6 = 9x
Subtract 9x from both sides.
3x 6 = 0
3x = 6
I assume you can carry on from there. 
12x6=9x8

12x6=9x
first step: subtract xvariables to oneside 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 
x=2
