Question

2.(7x + 2) + 12.(x + 1) = 2​

Answer 1

Resposta:

$x = -\frac{7}{13}$

Explicação passo-a-passo:

$2.(7x + 2) + 12.(x + 1) = 2\\14x + 4 + 12x + 12 = 2\\14x + 12x = 2 - 4 - 12\\26x = - 14\\x = -\frac{14}{26}$

Simplificando:

$x = -\frac{7}{13}$

Answer 2

Resposta:

2(7×+2)+12(×+1)=2

14×+4+12×12=2

14×+12×= -4-12+2

26×= -14(simplifica por 2)
