Question

3 . (2-4 . (×-1) -3) +2 . (×-1) =0

Answer 1

3.[2 -4(x-1) -3] +2.(x-1)=0
3.(2 -4x +4 -3) +2x -2 =0
3(-4x +2 +1) +2x= 2
3(-4x +3) +2x =2
-12x +9 +2x =2
-12x +2x= 2-9
-10x =-7          .(-1)
10x =7
x= 7/10

Answer 2

3 . [2 - 4. (x - 1) - 3] +2 . (x - 1) = 0
3. [ 2 - 4x + 4 - 3] + 2x - 2 = 0
3 . [ 3 - 4x] + 2x - 2 = 0
9 - 12x + 2x - 2 = 0
- 12x + 2x - 2 + 9 = 0
- 10x + 7 = 0
- 10x = - 7 (-1)
  10x = 7
x = 7/10
