Express the last equation of each system as a sum of multiples of the first two equations.

Question:

Express the last equation of each system as a sum of multiples of the first two equations.
(a) x1 + x2 + x3 = 1
2x1 - x2 + 3x3 = 3
x1 - 2x2 + 2x3 = 2
(b) x1 + 2x2 - 3x3 = -3
x1 + 3x2 - 5x3 = 5
x1 - 2x2 + 5x3 = -35
