Answer 2

1) 5 + x = 12 + 10

5 + x = 22

x = 22 - 5

x = 17

2) 10 + x = 20 + 10

10 + x = 30

x = 30 - 10

x = 20

3) x + 2 = 10

x = 10 - 2

x = 8

4)5x = 20

x = 20/5

x = 4

5) 3x = 21

x = 21/3

x = 7

6) x - 8 = 10

x = 10 + 8

x = 18

7) 5x + 3 = 43

5x = 43 - 3

x = 40/5

x = 8

8) 7x = 56

x = 56/7

x = 8

9) x + 2 = 5

x = 5 - 2

x = 3

8) 4x -5 = 23

4x = 23 - 5

x = 18/4

x = 4.5

11) 9x + 7 = 25

9x = 25 - 7

x = 18/9

x = 2

12) 2x = 10

x = 10/2

x = 5

13) x - 3 = 10

x = 10 + 3

x = 13

14) 2x = 14

x = 14/2

x = 7

15) x + 9 = 20

x = 20 - 9

x = 11

16) 5x + 1 = 21

5x = 21 - 1

x = 20/5

x = 4

17) 3x = 24

x = 24/3

x = 8

18) 7x = 28

x = 28/7

x = 4
