Question

2(x-2)+5(2-x)+6(x+1)=0

Answer 1

2(x - 2) + 5(2 - x) + 6(x + 1) = 0
2x - 4 + 10 - 5x + 6x + 6 = 0
2x - 5x + 6x = -6 - 10 + 4
3x = -16 + 4
3x = -12
x = -12/3
x = -4

Resposta: -4

Espero ter ajudado.

Answer 2

2(x-2)+5(2-x)+6(x+1)=0
2x-4+10-5x+6x+6=0
2x-5x+6x=4-10-6
3x=-12
x=-12/3
x=-4

Bons estudos!!!
