Question

How many solutions does this equation have? 8m = 10 + 8m

Answer 1

8m-10=8-m

We move all terms to the left:

8m-10-(8-m)=0

We add all the numbers together, and all the variables

8m-(-1m+8)-10=0

We get rid of parentheses

8m+1m-8-10=0

We add all the numbers together, and all the variables

9m-18=0

We move all terms containing m to the left, all other terms to the right

9m=18

m=18/9

m=2
