Hello there!

The answer should be the third option C.

78 = -2(m + 3) + m

First you had to simplify from both sides of the equations.

78=-2(m+3)+m

78=(-2)(m)+(-2)(3)+m

78=-2m+-6+m

78=(-2m+m)+(-6)

78=-m+-6

78=-m-6

Then you can flip by the equation.

-m-6=78

Add by 6 from both sides.

-m-6+6=78+6

-m=84

Divide by -1 from both sides.

$\frac{-m}{-1}=\frac{84}{-1}$

Simplify should be the correct answer.

m=-84

Hope this helps!
