x+3\alpha =180
Swap sides so that all variable terms are on the left hand side.
x=180-3\alpha
Subtract 3\alpha from both sides.
x+3\alpha =180
Swap sides so that all variable terms are on the left hand side.
3\alpha =180-x
Subtract x from both sides.
\frac{3\alpha }{3}=\frac{180-x}{3}
Divide both sides by 3.
\alpha =\frac{180-x}{3}
Dividing by 3 undoes the multiplication by 3.
\alpha =-\frac{x}{3}+60
Divide 180-x by 3.
