    x – (5 – 3x + 2) = 15 + 3x <-- VERY SIMPLE equation. First we want to do distributive property. We want to distribute the negative sign to the (5-3x+2) So then the equation will become.. x-5+3x-2=15+3x Now that we have our new equation -> x-5+3x-2=15+3x Lets break it down a bit more, By combining like terms! We will combine our x's together. so.. x-5+3x-2=15+3x will become.. 4x-5-2=15+3x Now, that we have combined our x's on one side, let us also combine the simple numbers together. So.. 4x-5-2=15+3x will become.. 4x-7=15+3x Now that we have our new equation -> 4x-7=15+3x This will become very easy to solve! 4x-7=15+3x We can start by adding the 7 to both sides. 4x-7=15+3x +7 +7 ------------ 4x=22+3x now we will subtract 3x on both sides. 4x=22+3x -3x -3x ---------- x=22
