Question: Solve the system by the method of elimination and check any solutions algebraically. 1. 2. 3. fx + 2y = 6 lx 2y = 2

Solve the system by the method of elimination and check any solutions algebraically.
1.

fx + 2y = 6 lx – 2y = 2

2.

[Зх — 5у %3D 8 |2x + 5y = 22 2х

3.

fx + 2y = 6 lx 2y = 2 [ 5 %3D

fx + 2y = 6 lx 2y = 2 [ 5 %3D 8 |2x + 5y = 22 2
