100x+20y=35\times 180
Multiply both sides by 180.
100x+20y=6300
Multiply 35 and 180 to get 6300.
100x=6300-20y
Subtract 20y from both sides.
\frac{100x}{100}=\frac{6300-20y}{100}
Divide both sides by 100.
x=\frac{6300-20y}{100}
Dividing by 100 undoes the multiplication by 100.
x=-\frac{y}{5}+63
Divide 6300-20y by 100.
100x+20y=35\times 180
Multiply both sides by 180.
100x+20y=6300
Multiply 35 and 180 to get 6300.
20y=6300-100x
Subtract 100x from both sides.
\frac{20y}{20}=\frac{6300-100x}{20}
Divide both sides by 20.
y=\frac{6300-100x}{20}
Dividing by 20 undoes the multiplication by 20.
y=315-5x
Divide 6300-100x by 20.
