d-10x-10= -20
e-12x+12= -24


Me ajudem por favoree

Answer 1

A- 6x + 12= 6
6x= 6 - 12
6x= -6
X= -6/6
X=-1
B- 8x + 8= -16
8x= -16 - 8
8x= -24
X= -3
C- 9x + 9= -9
9x= -9+9
9x= 0
X= {}
D- 10x-10=-20
10x=-20+10
10x= -10
X= -1
E- 12x+12= -24
12x= -24-12
12x= -36
X= -3

Answer 2

Resolução:

a)

6x + 12 = 6

6x = 6 - 12

6x = - 6

x = - 6 / 6

x = - 1

b)

8x + 8 = - 16

8x = - 16 - 8

8x = - 24

x = - 24 / 8

x = - 3

c)

9x + 9 = - 9

9x = - 9 - 9

9x = - 18

x = - 18 / 9

x = - 2

d)

10x - 10 = - 20

10x = - 20 + 10

10x = - 10

x = - 10 / 10

x = - 1

e)

12x + 12 = - 24

12x = - 24 - 12

12x = - 36

x = - 36 / 12

x = - 3
