7x+3y-16x=-3
Subtract 16x from both sides.
-9x+3y=-3
Combine 7x and -16x to get -9x.
-9x=-3-3y
Subtract 3y from both sides.
-9x=-3y-3
The equation is in standard form.
\frac{-9x}{-9}=\frac{-3y-3}{-9}
Divide both sides by -9.
x=\frac{-3y-3}{-9}
Dividing by -9 undoes the multiplication by -9.
x=\frac{y+1}{3}
Divide -3-3y by -9.
3y=16x-3-7x
Subtract 7x from both sides.
3y=9x-3
Combine 16x and -7x to get 9x.
\frac{3y}{3}=\frac{9x-3}{3}
Divide both sides by 3.
y=\frac{9x-3}{3}
Dividing by 3 undoes the multiplication by 3.
y=3x-1
Divide 9x-3 by 3.
