\frac{1}{3}x=1+\frac{3}{8}y
Add \frac{3}{8}y to both sides.
\frac{1}{3}x=\frac{3y}{8}+1
The equation is in standard form.
\frac{\frac{1}{3}x}{\frac{1}{3}}=\frac{\frac{3y}{8}+1}{\frac{1}{3}}
Multiply both sides by 3.
x=\frac{\frac{3y}{8}+1}{\frac{1}{3}}
Dividing by \frac{1}{3} undoes the multiplication by \frac{1}{3}.
x=\frac{9y}{8}+3
Divide 1+\frac{3y}{8} by \frac{1}{3} by multiplying 1+\frac{3y}{8} by the reciprocal of \frac{1}{3}.
-\frac{3}{8}y=1-\frac{1}{3}x
Subtract \frac{1}{3}x from both sides.
-\frac{3}{8}y=-\frac{x}{3}+1
The equation is in standard form.
\frac{-\frac{3}{8}y}{-\frac{3}{8}}=\frac{-\frac{x}{3}+1}{-\frac{3}{8}}
Divide both sides of the equation by -\frac{3}{8}, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{-\frac{x}{3}+1}{-\frac{3}{8}}
Dividing by -\frac{3}{8} undoes the multiplication by -\frac{3}{8}.
y=\frac{8x}{9}-\frac{8}{3}
Divide 1-\frac{x}{3} by -\frac{3}{8} by multiplying 1-\frac{x}{3} by the reciprocal of -\frac{3}{8}.
