-x=5-7y
Subtract 7y from both sides.
\frac{-x}{-1}=\frac{5-7y}{-1}
Divide both sides by -1.
x=\frac{5-7y}{-1}
Dividing by -1 undoes the multiplication by -1.
x=7y-5
Divide 5-7y by -1.
7y=5+x
Add x to both sides.
7y=x+5
The equation is in standard form.
\frac{7y}{7}=\frac{x+5}{7}
Divide both sides by 7.
y=\frac{x+5}{7}
Dividing by 7 undoes the multiplication by 7.
