Determine if the given ordered pair is a solution to the system:

1.

2x + y = 5 (4, -3)
x - y = 1

2.

4x - y = -2 (-1, -2)
3x + y = -5

Solve each system of equations by the graphing method:

3.

x - y = 4
x + y = 2

4.

-4x + 4y = 4
y = x + 1

Solve each system of equations by the substitution method:

5.

8x + 3y = -14
-x + 2y = -3

6.

-3x + 2y = 8
y = 3/2x + 3

Solve each system of equations by the addition method:

7.

3x + 5y = 4
-4x + 2y = -1

8.

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