15x=-5y
Subtract 5y from both sides. Anything subtracted from zero gives its negation.
\frac{15x}{15}=-\frac{5y}{15}
Divide both sides by 15.
x=-\frac{5y}{15}
Dividing by 15 undoes the multiplication by 15.
x=-\frac{y}{3}
Divide -5y by 15.
5y=-15x
Subtract 15x from both sides. Anything subtracted from zero gives its negation.
\frac{5y}{5}=-\frac{15x}{5}
Divide both sides by 5.
y=-\frac{15x}{5}
Dividing by 5 undoes the multiplication by 5.
y=-3x
Divide -15x by 5.
