Question

12x - 14 ( 1 - x) - 2 (10x + 4)= 0

Answer 1

Olá,

Vamos lá,

12x - 14(1-x)-2(10x+ 4)= 0
12x - 14 +14x -20x-8=0
12x+14x-20x= 14 +8
26x-20x=22
6x=22
x=22/6
x=3,66

Answer 2

Resposta:

x=3,66

Explique passo-a-passo:

12x - 14(1-x)-2(10x+ 4)= 0

12x - 14 +14x -20x-8=0

12x+14x-20x= 14 +8

26x-20x=22

6x=22

x=22/6

x=3,66
