30x=-60y
Subtract 60y from both sides. Anything subtracted from zero gives its negation.
\frac{30x}{30}=-\frac{60y}{30}
Divide both sides by 30.
x=-\frac{60y}{30}
Dividing by 30 undoes the multiplication by 30.
x=-2y
Divide -60y by 30.
60y=-30x
Subtract 30x from both sides. Anything subtracted from zero gives its negation.
\frac{60y}{60}=-\frac{30x}{60}
Divide both sides by 60.
y=-\frac{30x}{60}
Dividing by 60 undoes the multiplication by 60.
y=-\frac{x}{2}
Divide -30x by 60.
