-4x=17-5y
Subtract 5y from both sides.
\frac{-4x}{-4}=\frac{17-5y}{-4}
Divide both sides by -4.
x=\frac{17-5y}{-4}
Dividing by -4 undoes the multiplication by -4.
x=\frac{5y-17}{4}
Divide 17-5y by -4.
5y=17+4x
Add 4x to both sides.
5y=4x+17
The equation is in standard form.
\frac{5y}{5}=\frac{4x+17}{5}
Divide both sides by 5.
y=\frac{4x+17}{5}
Dividing by 5 undoes the multiplication by 5.
