6x + 6=2x+42
A simple balancing problem.
First lets get all of the variables on the same side of the equal sign. We do that by subrtracting 2x from both sides.
6x + 6 -2x = 2x+42 -2x
That gives
4x + 6 = 42
Now we get all of the non variables on the other side by subtracting 6
4x + 6 - 6 = 42 - 6
That gives
4x = 36
Now we figure out what "X" is by dividing both sides by 4. That gets "X" by itself.
4x/4 = 36/4
That gives
x = 9

6x + 6= 2x + 42
6x - 2x +6 = 2x - 2x + 42
4x + 6 - 6 =42 - 6
4x=36
4x/4 = 36/4
x = 9

6x+6=2x+42
subtract 6 from both sides
6x=2x+36
subtract 2x from both sides
4x=36
divide both sides by 4
x=9
answer C

Combine the x's then the constants (reg 3's). Divide that number by what is in front of the x.
