    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.

    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.
