Rezolvați ecuațiile:

I. 1) x + 2 = 9 2) 3x – 1 = 8 3) 4x – 9 = 3 4) 5x – 9 = 1

5) 3 – 2x = 7 6) 2 – x = 8 7) 4 = x – 2 8) 3x + 1 = 10

9) 7x + 15 = 1 10) 3 – 4x = 15 11) x + 3 = 1 12) 7 – 2x = 9


II. 1) 3x – 6 = 2x + 1 2) 7 – 2x = 4x + 1 3) 6x – 1 = x + 9

4) 3 – 2x = x + 6 5) 9x + 1 = 2x + 15 6) 10x – 1 = 3x + 20

7) 12x – 7 = 10x + 1 8) 5 – 17x = 5x – 39 9) 18x – 9 = 6x + 27

10) 9x – 1 = 6x + 11 11) 20x + 5 = 7x – 21 12) 31x – 4 = 17x + 10

Va rog e urgent!!!! daca e posibil cu tot cu rezolvare.

1. x+2=9=> x=9-2=> x=7

2. 3x-1=8=> 3x=8+1=> 3x=9, x=9:3=3

3. 4x-9=3=> 4x=3+9=> 4x=12, x= 12:4=3

4. 5x-9=1=> 5x=9+1=> 5x=10, x=10:5=2

5. 3-2x=7=> 2x=7+3=> 2x=10, x= 10:2=5

6.2-x=8=> x=8+2=> x=10

7.4=x-2=> x=4+2=> x=6

8. 3x+1=10=> 3x=10-1=> 3x=9, x=9:3=3

9. 7x+15=1=> 7x=1-15=> 7x= -14, x=-14:7=-2

10. 3-4x=15=> 4x=15-3=> 4x=12, x=12:4=3

12. 7-2x=9=> 2x=9+7=> 2x=16, x=16:2=8

Sper ca am putut să te ajut macar la primul!
