2x-3=15.
Move all terms not containing X to the right side.
Equation now reads 2x=-3+15.
add the - 3 and 15 to get 12.
Equation now reads 2x=12.
Divide both sides by number in front of x.
Equation now reads 2x/2=12/2.
The solution is x=6.

First, you need to add 3 to both sides to isolate the variable x. 15-3=12, so now you have 2x=12. You only want x, not 2*x, so divide both sides by 2. 12/2 equals 6, so your variable x is equal to 6.
