If your trying to find x, distribute 2(x+6), which is by multiplying 2 times x, which is 2x and 2 times 6, which is 12. So your left off with 4x+2=2x+12. In order to find x, we have to move the 2 to the right, which will give us 2x+10 and then move 2x to the left to give us 2x=10. Divide both sides by 2, and x= 5.
