3x+y+9x-6=3
Multiply both sides of the equation by 3.
12x+y-6=3
Combine 3x and 9x to get 12x.
12x-6=3-y
Subtract y from both sides.
12x=3-y+6
Add 6 to both sides.
12x=9-y
Add 3 and 6 to get 9.
\frac{12x}{12}=\frac{9-y}{12}
Divide both sides by 12.
x=\frac{9-y}{12}
Dividing by 12 undoes the multiplication by 12.
x=-\frac{y}{12}+\frac{3}{4}
Divide 9-y by 12.
3x+y+9x-6=3
Multiply both sides of the equation by 3.
12x+y-6=3
Combine 3x and 9x to get 12x.
y-6=3-12x
Subtract 12x from both sides.
y=3-12x+6
Add 6 to both sides.
y=9-12x
Add 3 and 6 to get 9.
