Answer:

m=7

Step-by-step explanation:

Replace all occurrences of  +  −  with a single -. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅ − 1 = − 1

7(m-13)=-42

Divide each term by  7  and simplify.

m-13=-6

Move all terms not containing  m  to the right side of the equation.

m=7

Hope this helps!

Plz mark brainiest! =D

7(m+-13)=-42
(m+-13)=-42-7
(m+-13)=-49
m=-49+13
m=-36
