Answer:
(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
