Note: You made a mistake on the line "-12m=116"


-2%285%2B6m%29%2B16=-90 Start with the given equation.


-10-12m%2B16=-90 Distribute.


-12m%2B6=-90 Combine like terms on the left side.


-12m=-90-6 Subtract 6 from both sides.


-12m=-96 Combine like terms on the right side.


m=%28-96%29%2F%28-12%29 Divide both sides by -12 to isolate m.


m=8 Reduce.

Answer:

So the answer is m=8

-2(5+6m)+16=-90
-10+12m+16=-90
