y-8=\frac{4}{3}\left(x+5\right)
The opposite of -5 is 5.
y-8=\frac{4}{3}x+\frac{20}{3}
Use the distributive property to multiply \frac{4}{3} by x+5.
\frac{4}{3}x+\frac{20}{3}=y-8
Swap sides so that all variable terms are on the left hand side.
\frac{4}{3}x=y-8-\frac{20}{3}
Subtract \frac{20}{3} from both sides.
\frac{4}{3}x=y-\frac{44}{3}
Subtract \frac{20}{3} from -8 to get -\frac{44}{3}.
\frac{\frac{4}{3}x}{\frac{4}{3}}=\frac{y-\frac{44}{3}}{\frac{4}{3}}
Divide both sides of the equation by \frac{4}{3}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-\frac{44}{3}}{\frac{4}{3}}
Dividing by \frac{4}{3} undoes the multiplication by \frac{4}{3}.
x=\frac{3y}{4}-11
Divide y-\frac{44}{3} by \frac{4}{3} by multiplying y-\frac{44}{3} by the reciprocal of \frac{4}{3}.
y-8=\frac{4}{3}\left(x+5\right)
The opposite of -5 is 5.
y-8=\frac{4}{3}x+\frac{20}{3}
Use the distributive property to multiply \frac{4}{3} by x+5.
y=\frac{4}{3}x+\frac{20}{3}+8
Add 8 to both sides.
y=\frac{4}{3}x+\frac{44}{3}
Add \frac{20}{3} and 8 to get \frac{44}{3}.
