3w_{2}=w-20w_{2}
Combine -43w_{2} and 23w_{2} to get -20w_{2}.
w-20w_{2}=3w_{2}
Swap sides so that all variable terms are on the left hand side.
w=3w_{2}+20w_{2}
Add 20w_{2} to both sides.
w=23w_{2}
Combine 3w_{2} and 20w_{2} to get 23w_{2}.
3w_{2}=w-20w_{2}
Combine -43w_{2} and 23w_{2} to get -20w_{2}.
3w_{2}+20w_{2}=w
Add 20w_{2} to both sides.
23w_{2}=w
Combine 3w_{2} and 20w_{2} to get 23w_{2}.
\frac{23w_{2}}{23}=\frac{w}{23}
Divide both sides by 23.
w_{2}=\frac{w}{23}
Dividing by 23 undoes the multiplication by 23.
