Solve by substitution.
1.
y = 2
4 x - 2 y = 8
2.
x = y - 1
x + 2 y = 5
3.
2 x + y = 9
y = x - 3
4.
4 x - y = 9
y = 2 x - 5
5.
4 x + y = 3
5 y + 2 x = -3
6.
2 x + y = 0
3 x - 2 y = 7
7.
y = 2 x + 3
y = 4 x - 1
8.
y = -3 x + 4
y = -5 x + 10
9.
y = 2 x - 9
y = 4 x - 23
10.
- x + 8 y = -7
2 x + 5 y = -7
