Solve the equation. 4( r $-$ 4) + 3( r $-$ 1) = $-$ 3( r $-$ 1) + 11( r + 2)
A) r = -48
B) r = -43
C) r = -49
D) r = -34
E) r = -44

Quizplus · Accepted Answer

Expand all the brackets in the equation and simplify.
4r - 16 + 3r - 3 = -3r + 3 + 11r + 22
7r - 19 = 8r + 25
Subtract 7r from both sides
-r - 19 = 25
Add 19 to both sides
-r = 44
Multiply both sides by -1
r = -44

Therefore, the best choice is E.
