Solving for variable 'w'.

Move all terms containing w to the left, all other terms to the right.

Add '-1x2' to each side of the equation.
w2 + x2 + y2 + -1x2 + z2 = 221 + -1x2

Reorder the terms:
w2 + x2 + -1x2 + y2 + z2 = 221 + -1x2

Combine like terms: x2 + -1x2 = 0
w2 + 0 + y2 + z2 = 221 + -1x2
w2 + y2 + z2 = 221 + -1x2

Add '-1y2' to each side of the equation.
w2 + y2 + -1y2 + z2 = 221 + -1x2 + -1y2

Combine like terms: y2 + -1y2 = 0
w2 + 0 + z2 = 221 + -1x2 + -1y2
w2 + z2 = 221 + -1x2 + -1y2

Add '-1z2' to each side of the equation.
w2 + z2 + -1z2 = 221 + -1x2 + -1y2 + -1z2

Combine like terms: z2 + -1z2 = 0
w2 + 0 = 221 + -1x2 + -1y2 + -1z2
w2 = 221 + -1x2 + -1y2 + -1z2

Simplifying
w2 = 221 + -1x2 + -1y2 + -1z2

Reorder the terms:
-221 + w2 + x2 + y2 + z2 = 221 + -1x2 + -1y2 + -1z2 + -221 + x2 + y2 + z2

Reorder the terms:
-221 + w2 + x2 + y2 + z2 = 221 + -221 + -1x2 + x2 + -1y2 + y2 + -1z2 + z2

Combine like terms: 221 + -221 = 0
-221 + w2 + x2 + y2 + z2 = 0 + -1x2 + x2 + -1y2 + y2 + -1z2 + z2
-221 + w2 + x2 + y2 + z2 = -1x2 + x2 + -1y2 + y2 + -1z2 + z2

Combine like terms: -1x2 + x2 = 0
-221 + w2 + x2 + y2 + z2 = 0 + -1y2 + y2 + -1z2 + z2
-221 + w2 + x2 + y2 + z2 = -1y2 + y2 + -1z2 + z2

Combine like terms: -1y2 + y2 = 0
-221 + w2 + x2 + y2 + z2 = 0 + -1z2 + z2
-221 + w2 + x2 + y2 + z2 = -1z2 + z2

Combine like terms: -1z2 + z2 = 0
-221 + w2 + x2 + y2 + z2 = 0
