4x-2-w+1+3-4w-22=2y
Combine 3x and x to get 4x.
4x-1-w+3-4w-22=2y
Add -2 and 1 to get -1.
4x+2-w-4w-22=2y
Add -1 and 3 to get 2.
4x+2-5w-22=2y
Combine -w and -4w to get -5w.
4x-20-5w=2y
Subtract 22 from 2 to get -20.
-20-5w=2y-4x
Subtract 4x from both sides.
-5w=2y-4x+20
Add 20 to both sides.
-5w=20+2y-4x
The equation is in standard form.
\frac{-5w}{-5}=\frac{20+2y-4x}{-5}
Divide both sides by -5.
w=\frac{20+2y-4x}{-5}
Dividing by -5 undoes the multiplication by -5.
w=\frac{4x}{5}-\frac{2y}{5}-4
Divide 20+2y-4x by -5.
4x-2-w+1+3-4w-22=2y
Combine 3x and x to get 4x.
4x-1-w+3-4w-22=2y
Add -2 and 1 to get -1.
4x+2-w-4w-22=2y
Add -1 and 3 to get 2.
4x+2-5w-22=2y
Combine -w and -4w to get -5w.
4x-20-5w=2y
Subtract 22 from 2 to get -20.
4x-5w=2y+20
Add 20 to both sides.
4x=2y+20+5w
Add 5w to both sides.
4x=2y+5w+20
The equation is in standard form.
\frac{4x}{4}=\frac{2y+5w+20}{4}
Divide both sides by 4.
x=\frac{2y+5w+20}{4}
Dividing by 4 undoes the multiplication by 4.
x=\frac{y}{2}+\frac{5w}{4}+5
Divide 2y+20+5w by 4.
