8y+2z+6w=-1-4x
Subtract 4x from both sides.
2z+6w=-1-4x-8y
Subtract 8y from both sides.
6w=-1-4x-8y-2z
Subtract 2z from both sides.
6w=-4x-8y-2z-1
The equation is in standard form.
\frac{6w}{6}=\frac{-4x-8y-2z-1}{6}
Divide both sides by 6.
w=\frac{-4x-8y-2z-1}{6}
Dividing by 6 undoes the multiplication by 6.
w=-\frac{z}{3}-\frac{2x}{3}-\frac{4y}{3}-\frac{1}{6}
Divide -1-4x-8y-2z by 6.
4x+2z+6w=-1-8y
Subtract 8y from both sides.
4x+6w=-1-8y-2z
Subtract 2z from both sides.
4x=-1-8y-2z-6w
Subtract 6w from both sides.
4x=-8y-2z-6w-1
The equation is in standard form.
\frac{4x}{4}=\frac{-8y-2z-6w-1}{4}
Divide both sides by 4.
x=\frac{-8y-2z-6w-1}{4}
Dividing by 4 undoes the multiplication by 4.
x=-\frac{z}{2}-\frac{3w}{2}-2y-\frac{1}{4}
Divide -1-8y-2z-6w by 4.
