-5x-19=7y
Add 7y to both sides. Anything plus zero gives itself.
-5x=7y+19
Add 19 to both sides.
\frac{-5x}{-5}=\frac{7y+19}{-5}
Divide both sides by -5.
x=\frac{7y+19}{-5}
Dividing by -5 undoes the multiplication by -5.
x=\frac{-7y-19}{5}
Divide 7y+19 by -5.
-7y-19=5x
Add 5x to both sides. Anything plus zero gives itself.
-7y=5x+19
Add 19 to both sides.
\frac{-7y}{-7}=\frac{5x+19}{-7}
Divide both sides by -7.
y=\frac{5x+19}{-7}
Dividing by -7 undoes the multiplication by -7.
y=\frac{-5x-19}{7}
Divide 5x+19 by -7.
