Ok so first you need to identify what you are looking for... you need to find x. to do that you need toge it on one side. so cancel out the "-2x" on the left side by adding 2x(on both sides, don't forget you add common variables). now you should have something like this... -15=8x+9 now all you have to do is get rid of the 9 by subtracting 9 on both sides you should have -24=8x With that, all you have to do now is divide 8 into both sides and it should look like a fraction now
-24/8=8x/8 the 8x/8 will cancel out the 8 and you will have -24/8=x Simplify that and you should get -3=x need me to explain it with fewer words?
