Solve the following pairs of simultaneous equations by method of substitution.
1. x β y = 1
x + y = 3
2. y β x = 1
x + y = 5
3. y = 4x + 4
x + y = 14
4. a = 4 β b
2a + b = 1
5. 5x β 2b = 1
x = 5 β 2b
6. x β y = 4
x + 2y = 10
7. a β 2b = 1
3a β 4b = 1
8. 4x β 3y = 1
x β 2y = 4
9. a + 2p = 4
x β 2y = 6
10. 2x + 3y = 5
βx + 2y = 8
11. y β x = 2
2y β 4x = 10
12. x + 6y = 22
2x + 10y = 38
13. 2x β y = 5
x + y = 4
14. x + y = 7
2x + y = 10
15. x + y = 144
2x β 3y = 63
