2a + b + -1a + -1b = 0

Reorder the terms:2a + -1a + b + -1b = 0

Combine like terms: 2a + -1a = 1a1a + b + -1b = 0

Combine like terms: b + -1b = 01a + 0 = 01a = 0

Solving1a = 0

Solving for variable 'a'.

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

Divide each side by '1'.a = 0
