Solve system by the substitution method.

1. y = 2x - 6
y = x - 5

2. 7x - 4y = 26
y = x - 5

------------------------------------------------------------------------------------
Solve each system by the addition method. If there is no solution or an infinite number of solutions, so state.

3.6x + 2y = 8
2x - y = 6

4. 7x - 2y = 8
-14x + 4y = 8
