hi!!! it's kesha and i would like to help!

First, Simplify
8(3m + 5) = 2m + -4

Reorder the terms:
8(5 + 3m) = 2m + -4
(5 * 8 + 3m * 8) = 2m + -4
(40 + 24m) = 2m + -4

Reorder the terms:
40 + 24m = -4 + 2m

Solving
40 + 24m = -4 + 2m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-2m' to each side of the equation.
40 + 24m + -2m = -4 + 2m + -2m

Combine like terms: 24m + -2m = 22m
40 + 22m = -4 + 2m + -2m

Combine like terms: 2m + -2m = 0
40 + 22m = -4 + 0
40 + 22m = -4

Add '-40' to each side of the equation.
40 + -40 + 22m = -4 + -40

Combine like terms: 40 + -40 = 0
0 + 22m = -4 + -40
22m = -4 + -40

Combine like terms: -4 + -40 = -44
22m = -44

Divide each side by '22'.
m = -2

Simplifying
m = -2
Finally, your answer would be m = -2
hope this helps!

You are in time-out because of the chatty, then rude, then vulgar things you posted. I'm told your math is quite good, so I'm hoping you'll practice excellent Jiskha netiquette when you get out of time-out.
