15x=-3-21y
Subtract 21y from both sides.
15x=-21y-3
The equation is in standard form.
\frac{15x}{15}=\frac{-21y-3}{15}
Divide both sides by 15.
x=\frac{-21y-3}{15}
Dividing by 15 undoes the multiplication by 15.
x=\frac{-7y-1}{5}
Divide -3-21y by 15.
21y=-3-15x
Subtract 15x from both sides.
21y=-15x-3
The equation is in standard form.
\frac{21y}{21}=\frac{-15x-3}{21}
Divide both sides by 21.
y=\frac{-15x-3}{21}
Dividing by 21 undoes the multiplication by 21.
y=\frac{-5x-1}{7}
Divide -3-15x by 21.
