First, in the rule, 8x+15=3x-20, you have to get the x's on the left side by subtracting 3x, on both sides. then it would be, 5x+15=-20.
so you have to get the numbers on the other side, so you will have to subtract 15 to both sides, so you get 5x=-35, then you divide both sides by 5.
So, it's x=-7.
So, the answer is -7.
