4g+r=2r-2x solve for x

(r-4g) / 2 = x

Step-by-step explanation:

4g+r=2r-2x

To solve for x, subtract 2r from each side

4g+r-2r=2r-2r-2x

4g - r = - 2x

Divide by - 2 to isolate x

(4g-r) / -2 = - 2x/-2

(4g-r) / -2 = x

I will distribute the - inside the parentheses

(-4g + r) / 2 = x

And change the order in side the parentheses

(r-4g) / 2 = x
