2x+4+4y+z+2w-4=90
Multiply both sides of the equation by 2.
2x+4y+z+2w=90
Subtract 4 from 4 to get 0.
4y+z+2w=90-2x
Subtract 2x from both sides.
z+2w=90-2x-4y
Subtract 4y from both sides.
2w=90-2x-4y-z
Subtract z from both sides.
2w=90-z-4y-2x
The equation is in standard form.
\frac{2w}{2}=\frac{90-z-4y-2x}{2}
Divide both sides by 2.
w=\frac{90-z-4y-2x}{2}
Dividing by 2 undoes the multiplication by 2.
w=-\frac{z}{2}-x-2y+45
Divide 90-2x-4y-z by 2.
2x+4+4y+z+2w-4=90
Multiply both sides of the equation by 2.
2x+4y+z+2w=90
Subtract 4 from 4 to get 0.
2x+z+2w=90-4y
Subtract 4y from both sides.
2x+2w=90-4y-z
Subtract z from both sides.
2x=90-4y-z-2w
Subtract 2w from both sides.
2x=90-2w-z-4y
The equation is in standard form.
\frac{2x}{2}=\frac{90-2w-z-4y}{2}
Divide both sides by 2.
x=\frac{90-2w-z-4y}{2}
Dividing by 2 undoes the multiplication by 2.
x=-\frac{z}{2}-w-2y+45
Divide 90-4y-z-2w by 2.
