Question

ayudenme no entiendo​

Answer 1

1-. x - 13 = 88

x = 88 + 13

x = 101

2-. 4 + x = 25

x = 25 - 4

x = 21

3-. 24 - y = 48

-y = 48 - 24

y = -24

4-. -12 - x = 34

-x = 34 + 12

x = 46

5-. x + 23 = - 45

x = -45 - 23

x = -68

6-. -3y + 15 = 12

-3y = 12 - 15

-3y = -3

y = 1

7-. 5 - 2y = 43

-2y = 43 - 5

-2y = 38

y = - 19

8-. 12 + 4y = 36

4y = 36 - 12

4y = 24

y = 6

9-. 25 - 5z = 105

-5z = 105 - 25

-5z = 80

z = -16

Listo!!
