1/4x - 3/8x = 2
8(1/4x) - 8(3/8x) = 8(2)
2x - 3x = 16
- x = 16
-1(- x) = -1(16
x = - 16
- - - - - - - - -
1/3x - 1/3 = - 5
1/3x - 1/3 + 1/3 = - 5 + 1/3
1/3x = - 15/3 + 1/3
1/3x = - 14/3
3(1/3x) = - (3)(14/3)
x = - 42/3
x = - 14

i)1/4x-3/8x=2
2/8x -3/8x=2
x(-1/8) = 2
x = -16
ii)1/3x-1/3=-5
1/3x=-4/2/3
x =-14

1/4x-3/8x=2 find LCD on LHS
2x/8-3x/8=2
-x/8=2
x=-16
unless x is in the denominator, in which case
1/4x-3/8x=2
2/8-3/8=2x
-1/8=2x
x=-116
next question
1/3x-1/3=-5
if you mean
x/3-1/3=-5
x/3-1/3=-15/3
x/3=14/3
x=14
or if you mean for x to be in the denominator
1/3x-1/3=-5
1/3-x/3=-5x
1/3=-14x/3
1=-14x
x=-1/14

First Question
I am guessing that question should read as:-
(1/4)x - (3/8)x = 2
2x - 3x = 16
- x = 16
x = - 16
Next Question!
(1 / 3).x - (1/3) = - 5
x - 1 = - 15
x = - 14

1/4x-3/8x=2
LCF(4 and 8) = 8
2x - 3x = 16
-x = 16
x = -16
....
1/3x-1/3=-5
x/3 = -5 + 1/3
x/3 = -14/3
x = -14

if your question is
1/(4x) - 3/(8x) = 2
then, multiply both sides by 8x
2 - 3 = 16x
-1 = 16x
x=-1/16
second question:
1/(3x) - 1/3 = 5
1/(3x) = 5 + 1/3
1/(3x) = 16/3
1/x = 16
x = 1/16
