1-y-6x-9=0
Multiply both sides of the equation by 3.
-8-y-6x=0
Subtract 9 from 1 to get -8.
-y-6x=8
Add 8 to both sides. Anything plus zero gives itself.
-6x=8+y
Add y to both sides.
-6x=y+8
The equation is in standard form.
\frac{-6x}{-6}=\frac{y+8}{-6}
Divide both sides by -6.
x=\frac{y+8}{-6}
Dividing by -6 undoes the multiplication by -6.
x=-\frac{y}{6}-\frac{4}{3}
Divide 8+y by -6.
1-y-6x-9=0
Multiply both sides of the equation by 3.
-8-y-6x=0
Subtract 9 from 1 to get -8.
-y-6x=8
Add 8 to both sides. Anything plus zero gives itself.
-y=8+6x
Add 6x to both sides.
-y=6x+8
The equation is in standard form.
\frac{-y}{-1}=\frac{6x+8}{-1}
Divide both sides by -1.
y=\frac{6x+8}{-1}
Dividing by -1 undoes the multiplication by -1.
y=-6x-8
Divide 8+6x by -1.
