Question

Solve the equation 5m+4m=72

Answer 1

Hello my friend

9m=72

Divide both sides by 9 so you can find the value for m

9m/9=72/9

m=8

I hope that's help:)

Answer 2

First of all we group our m's together.
So first add
5m + 4m = 9m

Now lets set up our equation again
9m = 72 .... divide both sides by 9 to get m alone
÷9 = ÷9
************ now m is alone on the left side and we solve on the right side.
m = 8

So your answer is
m = 8
