Question

I don’t understand 8(3m+5)=2m-4

Answer 1

m= -2

Explanation:

Using PEMDAS, (3m+5) is first, so 3(-2)+5 is -1. 8 times -1 is -8. 2(-2) is -4 and -4 is -8.

Answer 2

m = -2

Explanation:

`8(3m + 5) = 2m - 4\\\\24m + 40 = 2m - 4\\\\22m = -44\\\\m = -2`

First, distribute and then combine like terms. Then isolate the variable.
