13x=1-25y
Subtract 25y from both sides.
\frac{13x}{13}=\frac{1-25y}{13}
Divide both sides by 13.
x=\frac{1-25y}{13}
Dividing by 13 undoes the multiplication by 13.
25y=1-13x
Subtract 13x from both sides.
\frac{25y}{25}=\frac{1-13x}{25}
Divide both sides by 25.
y=\frac{1-13x}{25}
Dividing by 25 undoes the multiplication by 25.
