\frac{3}{10}x=1-y
Subtract y from both sides.
\frac{\frac{3}{10}x}{\frac{3}{10}}=\frac{1-y}{\frac{3}{10}}
Divide both sides of the equation by \frac{3}{10}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{1-y}{\frac{3}{10}}
Dividing by \frac{3}{10} undoes the multiplication by \frac{3}{10}.
x=\frac{10-10y}{3}
Divide 1-y by \frac{3}{10} by multiplying 1-y by the reciprocal of \frac{3}{10}.
y=1-\frac{3}{10}x
Subtract \frac{3}{10}x from both sides.
