Question

(X-3)+(x+2)+2(x-1)-5=0

Answer 1

(x - 3) + (x + 2) + 2(x - 1) - 5 = 0
x - 3 + x + 2 + 2x - 2 - 5 = 0
x + x + 2x - 3 + 2 - 2 - 5 = 0
4x - 8 = 0
4x = 8
x = 8/4
x = 2

R.: x = 2

Answer 2

(x-3) + (x+2) +2(x-1) - 5 = 0
x - 3 +x +2 +2x -2 -5 = 0
x +x +2x = +3 -2 +2 + 5
4x = 8
x =  8 
      4
x = 2
