X^2+y^2+z^2=77

Solution for X^2+y^2+z^2=77 equation:

Simplifying
X2 + y2 + z2 = 77

Solving
X2 + y2 + z2 = 77

Solving for variable 'X'.

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

Add '-1y2' to each side of the equation.
X2 + y2 + -1y2 + z2 = 77 + -1y2

Combine like terms: y2 + -1y2 = 0
X2 + 0 + z2 = 77 + -1y2
X2 + z2 = 77 + -1y2

Add '-1z2' to each side of the equation.
X2 + z2 + -1z2 = 77 + -1y2 + -1z2

Combine like terms: z2 + -1z2 = 0
X2 + 0 = 77 + -1y2 + -1z2
X2 = 77 + -1y2 + -1z2

Simplifying
X2 = 77 + -1y2 + -1z2

Reorder the terms:
-77 + X2 + y2 + z2 = 77 + -1y2 + -1z2 + -77 + y2 + z2
