Check whether the ordered pair is a solution of the system.
5. (6, -1)
4x – y = 25
-3x – 2y = -16
6. (3, 0)
-x + 2y = 3
10x + y = 30
7. (-2, -8)
2x – y = 52
9x – y = -10
8. (-4, 1)
-4x + 3y = 19
5x – 7y = -27
9. (-5, 8)
3x = -31 + 2y
5x + 6y = 23
10. (0, 2)
2x + 4y = 6
7x = 4 + 3y
Solve each system of equations by graphing. Check each solution algebraically.
11. y = 2x – 4
y = -3x + 1
13. y = 3x – 8
y=x–8
14. x + 2y = 6
2x + y = 9
15. 2x + 3y = 12
2x – y = 4
16. 3x – 7y = -6
x + 2y = 11
17. 5x – 11 = 4y
7x – 1 = 8y
