Answer 2

Respuesta:

38, 6, 23, 6, 12, 5, 2, 5, 3, 3

Explicación paso a paso:

-15 + x = 23

x = 23 + 15

x = 38

2x + 5 = 17

2x = 17 - 5

2x = 12

x = 12/2

x = 6

8 + z = -15

z = -15 - 8

z = -23

6x - 6 = 30

6x = 30 + 6

6x = 36

x = 36/6

x = 6

y - 5 = 7

y = 7 + 5

y = 12

3x - 5 = 10

3x = 10 + 5

3x = 15

x = 15/3

x = 5

20x = 40

x = 40/20

x = 2

7x + 3 = 38

7x = 38 - 3

7x = 35

x = 35/7

x = 5

15y = 45

y = 45/15

y = 3

11h = 33

h = 33/11

h = 3
