Question 324751: 2x-8=4x-12

You can put this solution on YOUR website! To solve this problem for x, you want to get x by itself by combining like terms.
First, add 12 to each side of the equation:
2x-8=4x-12
2x-8+12 = 4x-12+12
2x+4=4x
Now we want to bring the x variables to the same side. To do this, we are going to subtract 2x from each side:
2x+4 = 4x
2x+4-2x = 4x-2x (to subtract 2x from 4x, just subtract the coefficients: 4x-2x = (4-2)x = 2x)
4 = 2x
Finally, divided each side by 2:
4 = 2x
4/2 = 2x/2
2=x
So your answer is x=2.
