y+4=\frac{1}{3}x+\frac{2}{3}
Use the distributive property to multiply \frac{1}{3} by x+2.
\frac{1}{3}x+\frac{2}{3}=y+4
Swap sides so that all variable terms are on the left hand side.
\frac{1}{3}x=y+4-\frac{2}{3}
Subtract \frac{2}{3} from both sides.
\frac{1}{3}x=y+\frac{10}{3}
Subtract \frac{2}{3} from 4 to get \frac{10}{3}.
\frac{\frac{1}{3}x}{\frac{1}{3}}=\frac{y+\frac{10}{3}}{\frac{1}{3}}
Multiply both sides by 3.
x=\frac{y+\frac{10}{3}}{\frac{1}{3}}
Dividing by \frac{1}{3} undoes the multiplication by \frac{1}{3}.
x=3y+10
Divide y+\frac{10}{3} by \frac{1}{3} by multiplying y+\frac{10}{3} by the reciprocal of \frac{1}{3}.
y+4=\frac{1}{3}x+\frac{2}{3}
Use the distributive property to multiply \frac{1}{3} by x+2.
y=\frac{1}{3}x+\frac{2}{3}-4
Subtract 4 from both sides.
y=\frac{1}{3}x-\frac{10}{3}
Subtract 4 from \frac{2}{3} to get -\frac{10}{3}.
