5y+14+2yr=8y
Swap sides so that all variable terms are on the left hand side.
14+2yr=8y-5y
Subtract 5y from both sides.
14+2yr=3y
Combine 8y and -5y to get 3y.
2yr=3y-14
Subtract 14 from both sides.
\frac{2yr}{2y}=\frac{3y-14}{2y}
Divide both sides by 2y.
r=\frac{3y-14}{2y}
Dividing by 2y undoes the multiplication by 2y.
r=\frac{3}{2}-\frac{7}{y}
Divide 3y-14 by 2y.
8y-5y=14+2yr
Subtract 5y from both sides.
3y=14+2yr
Combine 8y and -5y to get 3y.
3y-2yr=14
Subtract 2yr from both sides.
\left(3-2r\right)y=14
Combine all terms containing y.
\frac{\left(3-2r\right)y}{3-2r}=\frac{14}{3-2r}
Divide both sides by 3-2r.
y=\frac{14}{3-2r}
Dividing by 3-2r undoes the multiplication by 3-2r.
