(pfv me ajudem eu preciso pra hoje)







​

Answer 1

Resposta:

a) 4

b) 2

c) 3

d) 21

e) 9

f) 5

g) 10

h) 12

i) 4

j) 4

Explicação passo-a-passo:

a) 2 + x = 6

x = 6 - 2

x= 4

b) 4x +1 = 9

4x = 9 - 1

4x = 8

x= 8/4

x= 2

c) 5x -3 = 12

5x = 12 + 3

5x = 15

x= 15/5

x= 3

d) x/3 = 7

x= 7.3

x= 21

e) x - 5 = 4

x= 4 + 5

x= 9

f) x + 4 = 9

x = 9 - 4

x= 5

g) 2x/5 = 4

2x = 4.5

2x = 20

x= 20/2

x=10

h) 3x -4 = 2x +8

3x - 2x = 8 + 4

x= 12

i) 7x -2 +4 = 10 +5x

7x - 5x = 10 +2 -4

2x = 8

x= 8/2

x= 4

j) 6x = 2x +16

6x - 2x = 16

4x = 16

x= 16/4

x=4
