You can put this solution on YOUR website! 4x+3=15-2x --------->Subtract (3)
4x+3-3=15-3-2x
4x+0=12-2x ----------> add (2x)
4x+2x=12-2x+2x
(4+2)x=12+0
6x=12 --------->Divide by 6
x=2
OK

You need to get x on one side and solve, everything you do on one side you need to do on the other.
LHS subtract 3, RHS subtract 3
4x=15-2x-3
LHS add 2x, RHS add 2x
4x+2x=15-3
simplify like terms
6x=12
divide by 6 to get x by itself
x=2
