Solving for variable 'a'.

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

Add '-1b2' to each side of the equation.
a2 + b2 + -1b2 = -1b2 + x2

Combine like terms: b2 + -1b2 = 0
a2 + 0 = -1b2 + x2
a2 = -1b2 + x2

Simplifying
a2 = -1b2 + x2

Reorder the terms:
a2 + b2 + -1x2 = -1b2 + b2 + x2 + -1x2

Combine like terms: -1b2 + b2 = 0
a2 + b2 + -1x2 = 0 + x2 + -1x2
a2 + b2 + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
a2 + b2 + -1x2 = 0
