ayuda porfis​

Answer 1

Respuesta:

y - 11 = -4

y = -4 + 11

y = 7

x/9-9=1

x/9 = 1 + 9

x = 10 . 9

x = 90

y+5.4=-0.7

y + 20 = - 7/10

y = -7/10 - 20

y = -207/10

3+5a=8-40a+6

5a + 40a = 8 + 6 -3

45a = 11

a = 11/45

x+4x-2+x=28

6x = 28 + 2

6x = 30

x = 30/6

x = 5

x/3=6

x = 6 . 3

x = 18

1.5x=3.45

x = 3.45 /1.45

x = 2,3
