It’s 80
62=(-18)-m
We move all terms to the left:
62-((-18)-m)=0
We calculate terms in parentheses: -((-18)-m), so:
(-18)-m
determiningTheFunctionDomain
-m+(-18)
We add all the numbers together, and all the variables
-1m-18
Back to the equation:
-(-1m-18)
We get rid of parentheses
1m+18+62=0
We add all the numbers together, and all the variables
m+80=0
We move all terms containing m to the left, all other terms to the right
