Answer

The solution set is $\boxed{7}$

Steps

Step 1 ：Simplify the equation $rac{4 r+4}{8}=rac{2 r-6}{2}$ to $r/2 + 1/2 = r - 3$

Step 2 ：Solve the equation to isolate r, resulting in r = 7

Step 3 ：Substitute r = 7 into the equation to verify that both sides of the equation are equal

Step 4 ：The solution set is $\boxed{7}$
