-7x=-49-7y
Subtract 7y from both sides.
-7x=-7y-49
The equation is in standard form.
\frac{-7x}{-7}=\frac{-7y-49}{-7}
Divide both sides by -7.
x=\frac{-7y-49}{-7}
Dividing by -7 undoes the multiplication by -7.
x=y+7
Divide -49-7y by -7.
7y=-49+7x
Add 7x to both sides.
7y=7x-49
The equation is in standard form.
\frac{7y}{7}=\frac{7x-49}{7}
Divide both sides by 7.
y=\frac{7x-49}{7}
Dividing by 7 undoes the multiplication by 7.
y=x-7
Divide -49+7x by 7.
