me ajudem!
​

Answer 1

Resposta:

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

Explicação passo-a-passo:

$2(7x+2)+12(x+1)=2\to\\\\14x+4+12x+12=2\to\\\\14x+12x=2-12-4\to\\\\26x=-14\to\\\\x=-\dfrac{14}{26}\,\to\text{simplificando}\,\to\\\\\boxed{x=-\dfrac{7}{13}}\checkmark$

É isso!!

Answer 2

resolução!

2 ( 7x + 2 ) + 12 ( x + 1 ) = 2

14x + 4 + 12x + 12 = 2

26x = - 14

X = - 14/26

X = - 7/13
