Answer 1

Răspuns:

1. x=2

2. x=3

3. x=1

4. x+2=2:16

5.×=6

6.×=2

7.×=158

8.×=8

9.×=5

10.×=9

11.×=15

12.×=15

Answer 2

1. 3x=6
x= 6:3
x = 2

2. 2x=6
x= 6:2
x=3

3. 15x-3=12
15x= 15
x= 15:15
x=1

4. x+2 = 32
x= 32 -2
x=30

5. x-3=3
x= 3+3
x= 6

6. x+5= 7
x= 7-5
x=2

7. 2x-40=276
2x= 316
x= 158

8. 8x=64
x=8

9. 4x=20
x=5

10. x-1= 32
x= 32+1
x=33

11. 75-4x=15
4x= -60
x= -15

12. x-5=10
x= 10+5
x=15

13. 5x=60
x= 60:5
x=12
