Question

(x-3)-(x+2)+2 (x-1)-5=0
Qual é a resposta ?????

Answer 1

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

Answer 2

(x-3)-(x+2)+2*(x-1)-5=0
x-3-(x+2)+2*(x-1)-5=0
x-8-(x+2)+2*(x-1)=0
x-8-x-2+2*(x-1)=0
0-8-2+2*(x-1)=0
-8-2+2*(x-1)=0
-10+2*(x-1)=0
-10+2x-2=0
-12+2x=0
2x=12
x=12/2
x=6
