Question

-3.(2x-1)+2(x+4)=5.(x+3) alguém me ajuda​

Answer 1

Resposta:

$-3.(2x-1)+2(x+4)=5.(x+3)\\-6x + 3 + 2x + 8 = 5x + 15\\-6x + 2x - 5x = 15 - 3 - 8\\-9x = 4\\x = -\frac{4}{9}$

Explicação passo-a-passo:

Answer 2

$- 6x + 3 + 2x + 8 = 5x + 15$

$- 6x + 2x - 5x = 15 - 8 - 3$

$- 9x = 4$

$x = - \dfrac{4}{9}$
