D) 6x+36=72

E) 7x+49=98

F) 8x+64=124​

Answer 1

Resposta:

a) 2x +2 +5 = 0

x = -7/2

b) 3x =6

x= 2

c) 5x = 15

x = 3

d) 6x = 36

x = 6

e) 7x = 49

x= 7

f) 8x = 60

x = 60/8

Answer 2

A) 2(x+1) + 5 ???????

2x+2 +5

2x +7

B) 3x+6=12

3x =12-6

3x=6

x =6/3

x = 2

c) 5×+12=27

5x = 27 -12

5x = 15

x = 15/5

x = 3

D) 6x+36=72

6x =72-36

6x=36

x=36/6

x=6

E) 7x+49=98

7x=98 -49

7x =49

x =49/7

x = 7

F) 8x+64=124

8x = 124 -64

8x = 60

x= 60/8= 30/4= 15/2
