r=26

Explanation:

To solve for r, we need to rearrange the equation in such a way that r is isolated on one of the sides we can do that by doing the inverse of operations to both sides of the equation.

-(-8)/(r+6) = 1/4

(-1)/1*((-8)/(r+6)) = 1/4, whether it's (-1)/1 or 1/-1 doesn't matter.

8/(r+6) = 1/4

8=(1/4) * (r+6)

8/(1/4) = r+6

8*4 = r+6

32 = r+6

32 -6 = r

r=26
