-3R+2=5R+2-R
Combine 2R and -5R to get -3R.
-3R+2=4R+2
Combine 5R and -R to get 4R.
-3R+2-4R=2
Subtract 4R from both sides.
-7R+2=2
Combine -3R and -4R to get -7R.
-7R=2-2
Subtract 2 from both sides.
-7R=0
Subtract 2 from 2 to get 0.
R=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -7 is not equal to 0, R must be equal to 0.
