Answer :

Multiply -60(2-x) = 300-120+60x combine like terms 180+60x you can stop their Or continue subtract 60x from both sides and you'll have 180=-60x divide 60 from both sides and you'll have x=-3
so PEMDAS so first you distribute the -30(2-x) and get -120-(-60x) or -120+60x
then you do the rest
300-120+60x
180+60x
factor out the 60
60(3+x)
but the simplest form is 180+60x but both should work
