15x-17=-x+7 solve.
16x = 24 by adding x at both sides of the equation
x=(24/16) dividing both sides by 16
x=3/2 = 1.5

Solve. 15x-17= -x+7
1. We have a positive 15x and one negative x. By kicking off the -x to the other side, it now becomes +. We now have :
16x-17=7
2. We want to leave x by itself so that we may find its value. so we want to take the -17 and kick it off to the other side. By doing this, the -17 now becomes a +17 leaving us with:
16x=7+17
16x=24
3. We now want to get rid of the 16 by dividing so that we may leave x all by itself. To do this we want to divide on both sides.
16x/16=24/16
x (who is now alone)=24/16
x=1.5
