Question

a) 2.(2x+4) = 3 (x-1)





4.(x+1)-3.(2x+1)=10.(2x+1)​

Answer 1

Resposta:

a) -11; -9/22.

Explicação passo a passo:

A) 2.(2x + 4) = 3 (x - 1)

4x + 8 = 3x - 3

4x - 3x = - 3 - 8

x = - 11.

b) 4.(x + 1) - 3.(2x + 1) = 10.(2x + 1)​

4x + 4 - 6x - 3 = 20x + 10

4x - 6x - 20x = 10 - 4 + 3

- 2x - 20x = 6 + 3

- 22x = 9  .(-1)

22x = - 9

x = - 9/22.
