215x=1-107y
Subtract 107y from both sides.
\frac{215x}{215}=\frac{1-107y}{215}
Divide both sides by 215.
x=\frac{1-107y}{215}
Dividing by 215 undoes the multiplication by 215.
107y=1-215x
Subtract 215x from both sides.
\frac{107y}{107}=\frac{1-215x}{107}
Divide both sides by 107.
y=\frac{1-215x}{107}
Dividing by 107 undoes the multiplication by 107.
