Explanation:
We're basically trying to rearrange the equation to make everything equal x instead of y.
The biggest thing to note here is that x has to be positive. In order to make x positive, we need to switch the signs of everything in the equation.
So it'll go a little something like this:
y = x - 8
y - x = -8
-x = -y - 8
x = y + 8
Answer:
x = y + 8
