7x=3-10y
Subtract 10y from both sides.
\frac{7x}{7}=\frac{3-10y}{7}
Divide both sides by 7.
x=\frac{3-10y}{7}
Dividing by 7 undoes the multiplication by 7.
10y=3-7x
Subtract 7x from both sides.
\frac{10y}{10}=\frac{3-7x}{10}
Divide both sides by 10.
y=\frac{3-7x}{10}
Dividing by 10 undoes the multiplication by 10.
