Answer:
r=2
Explanation:
sub 16 frome each side: -12r=-24
divide both sides by -12: r=2
would have made it more detailed but im lazy rn, have a good day
r = 2
-12r + 16 = -8
Subtract 16 from both sides to isolate the r term.
-12r + 16 - 16 = -8 - 16
-12r = -24
Divide both sides by negative twelve.
-12r/-12 = -24/-12
Solve.
