7x=-2y
Subtract 2y from both sides. Anything subtracted from zero gives its negation.
\frac{7x}{7}=-\frac{2y}{7}
Divide both sides by 7.
x=-\frac{2y}{7}
Dividing by 7 undoes the multiplication by 7.
2y=-7x
Subtract 7x from both sides. Anything subtracted from zero gives its negation.
\frac{2y}{2}=-\frac{7x}{2}
Divide both sides by 2.
y=-\frac{7x}{2}
Dividing by 2 undoes the multiplication by 2.
