Question

1. x + 3(x – 1) = 6 – 4(2x + 3)
2. 5(x – 1) + 16(2x + 3) = 3(2x – 7) – x
3. 2(3x + 3) – 4(5x – 3) = x (x – 3) – x(x + 5)
4. 184 – 7(2x + 5) = 301 + 6(x – 1) – 6
5. 7(18 – x) – 6(3 – 5x) = - (7x + 9) – 3(2x + 5) – 12
6. 3x(x – 3) + 5(x + 7) – x(x + 1) – 2(x2 + 7) + 4 = 0
7. – 3(2x + 7) + (- 5x + 6) – 8(1 – 2x) – (x – 3) = 0
8. (3x – 4)(4x – 3) = (6x – 4)(2x – 5)
9. (4 – 5x)(4x – 5) = (10x – 3)(7 – 2x)
10. (x + 1)(2x + 5) = (2x + 3)(x – 4) + 5
11. (x – 2)2 – (3 – x)2 = 1
12. 14 – (5x – 1)(2x + 3) = 17 – (10x + 1)(x – 6)
13. (x – 2)2 + x(x – 3) = 3(x + 4)(x – 3) – (x + 2)(x – 1) + 2
14. (3x – 1)2 – 5(x – 2) – (2x + 3)2 – (5x + 2)(x – 1) = 0
15. 2(x – 3)2 – 3(x + 1)2 + (x – 5)(x – 3) + 4(x2 – 5x + 1) = 4x2 – 12
16. 5(x – 2)2 – 5(x + 3)2 + (2x – 1)(5x + 2) – 10x2 = 0
17. x2 – 5x + 15 = x(x – 3) – 14 + 5(x - 2) + 3(13 – 2x)
18. 3(5x – 6)(3x + 2) – 6(3x + 4)(x – 1) – 3(9x + 1)(x -2) = 0
19. 7(x – 4)2 – 3(x + 5)2 = 4(x + 1)(x – 1) – 2
20. 5(1 – x)2 – 6(x2 – 3x – 7) = x(x – 3) – 2x(x + 5) – 2
21. (x + 1)(x + 2)(x – 3) = (x – 2)(x + 1)(x + 1)
22. (x + 2)(x + 3)(x – 1) = (x + 4)(x + 4)(x – 4) + 7
23. (x + 1)3 – (x - 1)3 = 6x(x – 3)
24. 3(x – 2)2(x + 5) = 3(x + 1)2(x – 1) + 3
