6+4x+2+y=0
Add 2 and 4 to get 6.
8+4x+y=0
Add 6 and 2 to get 8.
4x+y=-8
Subtract 8 from both sides. Anything subtracted from zero gives its negation.
4x=-8-y
Subtract y from both sides.
4x=-y-8
The equation is in standard form.
\frac{4x}{4}=\frac{-y-8}{4}
Divide both sides by 4.
x=\frac{-y-8}{4}
Dividing by 4 undoes the multiplication by 4.
x=-\frac{y}{4}-2
Divide -8-y by 4.
6+4x+2+y=0
Add 2 and 4 to get 6.
8+4x+y=0
Add 6 and 2 to get 8.
4x+y=-8
Subtract 8 from both sides. Anything subtracted from zero gives its negation.
y=-8-4x
Subtract 4x from both sides.
