Question

Help me?? i need help.

Answer 1

r-h=x

Explanation:

You have to have x on one side and r and h on the other. When moving a variable/number to one side y have to make it the opposite sign.

r=x+h

r-h=x

Answer 2

`x = r - h`

Explanation:

When solving for x, we want to get x all by itself on one side of the equals side. It doesn't matter which side.

In this case, we have x + h. Since we want x alone we have to get rid of the h. We can do this by subtracting h from both sides (whatever you do to one side, you have to do to the other side).

`r = x + h \\ r - h = x + h - h \\ r - h = x`

Therefore, x = r - h.
