Question

Encontre o valor de x

A)3x=27 B)9x+x=100


C)9x-3x+5=41 D)3x+4x49​

Answer 1

Resposta:

A) 3x = 27

x = 27 : 3

x = 9

B) 9x + x = 100

10x = 100

x = 100 : 10

x = 10

C) 9x - 3x + 5 = 41

6x + 5 = 41

6x = 41 - 5

6x = 36

x = 36 : 6

x = 6

D) 3x + 4x = 49

7x = 49

x = 49 : 7

x = 7
