Consider this example that was provided:

2. Solve y 2 by elimination method. 2x (2) and (3) To eliminate z from Fquations 1, 2x+yz=2 o eliminate : from Equations (1) and (2) 3x + 2y 4 15x + 15y = IS (5) 12x+6y 62 = 12 To eliminate x from Equations (4) and (5) 15x+15y = 15 -15x- loy = -20 To find x, substitute 1 for y in equation 3x + = 4 Substitute 2 for x and 1 for y inEquauon (3) to find z. that the ordered triple (2, I, system. The solution set is ((2 Answer: I) satisfies all three equations in the original 1))
