estou muito confusa , realmente ñ sei como fazer :/
2.(7x + 2) +12.(x + 1) = 2
14x + 4 + 12x + 12 = 2
26x = -14
x = -14/26 = -7/13
pronto
Aplica a propriedade do "chuveirinho" ;-;
2 (7x + 2) + 12 (x + 1) = 2
26x + 16 = 2
26x = 2 - 16
x = -14/26
x = - 7/13
14x+4+12x+12=2
26x+16=2
26x=2-16
26x=-14
x=-14/26
===> simplificando x=-7/13
