Question

7X-1=6X+3

4X=3 (X-2)​

Answer 1

Olá,

7x - 1 = 6x + 3

7x − 1 − 6x = 6x + 3 − 6x

x − 1 = 3

x − 1 + 1 = 3 + 1

x = 4

4x = 3 (x - 2)

4x = (3 . x) + (3 . −2)

4x = 3x + −6

4x = 3x − 6

4x − 3x = 3x − 6 − 3x

x = −6

Answer 2

Resposta:

A) 7X-1=6X+3  ---> o 6X passa negativando, -1 passa positivando

7x -6x = 3 + 1

1x = 4

x = 4

B) 4X = 3 (X-2)​ ---> faça distributiva do 3 multiplicando o (x-2)

4x = (3 . x ) (3 . -2)

4x = 3x - 6 ---> 3x está positivo passará negativando

4x -3x = -6

1x = -6

Espero ter ajudado
