The simplified form of the expression is 1/12(13x - 36)
Using the expression given;
- 1/2(x-2)+1/3(x-3)+1/4(x-4)
1/2(x - 2) = x/2 - 1
1/3(x-3) = x/3 - 1
1/4(x-4) = x/4 - 1
Now we have :
x/2 - 1 + x/3 - 1 + x/4 - 1
x/2 + x/3 + x/4 - 3
(6x + 4x + 3x /12) - 3
13x/12 - 3
Factorize :
1/12(13x - 36)
Hence, the simplified form of the expression is 1/12(13x - 36)
