Question

Am nevoie de 40 de ecuatii de gradul intai (de gimnaziu).

Answer 1

 1. 7x - 3 = 2
2. 5x - 13 = 9
3. 11x -5 = 4
4. 2x - 7 = 3
5. x - 25 = 5
6. 30x - 5 = -5
7. 9x + 3 = 18
8. 35x - 7 = 10
9. 7x - 5= 2x + 13
10. 7(x-3 ) = 9(x+1)
11. 7(x-18 ) = 3(x-14)
12. 15 ( x-1 ) = 5
13. 25 ( x + 5 ) = 20
14. 50x - x = 7
15. 18x +9 = -3
16. x +20 = -1
17. 45x - 36 = 12
18. x(12 -6 ) = 15 -8
19. 22x - 20 = 17
20. 28x + 56 = 69
21. 50x = 90
22. 26 + x = 17
23. 100x + 50 = - 200
24. 99 + 2x = -1
25. 60x - 30 = 0
26. 20(x-50 ) = 36 ( x +x -x -1 )
27. 500x = 500-1
28. 40 -x = 68
29. -x+x-x+x = 98
30. 350x = 251 - 1
31. 96 +x = 3
32. -x = 200 - 198
33. x +1 = 92
34. 0,25x = 100
35. 1200 - x = 60
36. 1000x = 500
37. 33 + x = 11
38. 125x = 25
39. 320x = 80
40 . x(0,25 - 0,15 ) + x( 15 - 3) = 50

Sper ca te-am ajutat !!!
