    i would subtract 7 and divide by 4;

    4x + 7 = 15

    x = 2

    1. Isolate the variable. Subtract 7 from both sides of the equation. (4x+7-7 = 15-7)

    2. (4x = 8) This is what you should come up with after subtraction.

    3. Divide (4x=8) by 4 to isolate x.

    4. After dividing both sides by 4, (x=2) should be the answer.
