Answer:
r=4
Step-by-step explanation:
-4 (r+2) =4 (2-2r)
Divide each side by 4
-4/4 (r+2) =4/4 (2-2r)
-(r+2) = (2-2r)
Distribute
-r-2 = 2-2r
Add 2r to each side
-r+2r -2 = 2-2r+2r
r-2 =2
Add 2 to each side
r-2+2 =2+2
r=4
Check
-4 (r+2) =4 (2-2r)
-4 (4+2) =4(2-2*4)
-4(6) =4(2-8)
-24 = 4(-6)
-24 = -24
This checks
