Question

Gente me ajudem prfv!!!!!

Answer 1

Resposta:

a) x = -1

b) x = 3

c) x = 10

d) x = 6

e) x = 8

f) x = 2

Explicação passo-a-passo:

a)2x +6 = 4

2x = 4-6

2x = -2

x = -2/2

x = -1

b)3x - 2 = 7

3x = 7+2

3x = 9

x = 9/3

x = 3

c)10x - 100 = 0

10x = 0+100

x = 100/10

x = 10

d)6x - 36 = 0

6x = 36

x = 36/6

x = 6

e)4x - 32 = 0

4x = 32

x = 32/4

x = 8

f)7x - 14 = 0

7x = 14

x = 14/7

x = 2

Answer 2

Explicação passo-a-passo:

A)2x+6=4

2x=4-6

2x=-2

x=-2:2

x= -1

B)3x-2=7

3x=7+2

3x=9

x=9:3

x=3

C)10x-100=0

10x=+100

x=100:10

x=10

D)6x-36=0

6x=+36

x=36:6

x=6

E)4x-32=0

4x=+32

x=32:4

x=8

F)7x-14=0

7x=+14

x=14:7

x=2
