Question

a + 5 = - 2

b - 3 =-1

a - 3 = 17

Y + 4 = 30

2 - 6 = 10

a + 5 = - 8

(2)

3 x = 45

4a = - 32

5 x = - 20

- 2a = 16

6 x = 22

- 3z = 15

4x=29​

Answer 1

Resposta:

a = - 2 - 5

a = - 7

b = = - 1 + 3

b = 2

a = 17 + 3

a = 20

y = 30 - 4

y = 26

= 10 + 6 - 2

= 16 - 2

= 14

a = - 8 - 5

a = - 13

x = 45/3

x = 15

a = - 32/4

a = - 8

x = - 20/5

x = - 4

a = 16/ - 2

a = - 8

x = 22/6

x = 3,6

z = 15/ - 3

z = - 5

x = 29/4

x = 7,25
