PLEASE ANSWER WITH SOLUTION:
1. a + 3b = 9 7. 2r + 75 = 26
2a - 3b = o
2. x + y = -1 8. 4x - y = -2
3x - y = 5 3x + 2y = -7
3. f - 2g = 5 9. 2j - 3k = 3
3f + 2g = -9 3j + k = -23
4. 2c + 3d = -9 10. 3v - 2w = 11
7c - 3d = 1 v - 7w = 29
5. 5x - 2y = 11 11. 4a + 3b = 0
x + y = 5 7a - 2b = -29
6. 4e + 3f = 9 12. 5x - 4y = -1
e + f = 2 2x - 3y = 1
