Question

8r + 16 - 16r = -12r -16
solve for r
PLEASE check answer

Answer 1

8r + 16 - 16r = -12r -16

=> -8r + 16 = -12r - 16

=> -8r + 12r = -16 - 16

=> 4r = -32

=> r = -8

Verification:

Putting r = -8 in the given equation,

8(-8) + 16 - 16 (-8) = -12(-8) - 16

-64 + 16 + 128 = 96 - 16

-64 + 144 = 80

80 = 80
