Question

3. y = 2x - 6, y = 0
Solve the following simultaneous equations :
2. x + y = 5, x - y = 3
4. p = 2q - 1, q = 5 - 3p
5. 9x + 4y = 5, 4x - 5y = 9
6. x + 3y = 5, 3x - y = 5
7. 3x - 7y + 10 = 0, y - 2x - 3 = 0
8. 20u - 30v = 13, 10v - 10u = -5
9. 2x - 3y = 1.3, y - x = 0.5
10. 11x + 15y + 23 = 0, 7x - 2y - 20 = 0
11. 3 - (x - 5) = y + 2
2(x + y) = 4 - 3y

Answer 1

Solution: The given system may be written as. 2x + y − 5 = 0 4x + 2y − 10 = 0. The given ... kx − 2y + 6 = 0 4x + 3y + 9 = 0. The given ... 2x − 3y = 7 (k + 2)x − (2k + 1)y = 3(2k − 1).
