When solving the following equation, what is a possible first step to solving?

-2m + 3 = 5m + 7

a, divide both sides by x
b, add 5m to both sides
c, add 2m to both sides
d, subtract 2m from both sides

c, add 2m to both sides

Step-by-step explanation:

-2m + 3 = 5m + 7

Add 2m to both sides

-2m + 2m + 3 = 2m + 5m + 7

3 = 7m + 7

Subtract 7 from both sides

3 - 7 = 7m + 7 - 7

-4 = 7m

Divide both sides by 7

-4/7 = 7m/7

-4/7 = m

m = - 4/7
