Your question is kinda Incomplete.
But if asking for solving module.
lx-2l = l2x-3l
+/- (x - 2) = +/- (2x-3)
you have to take either negative on one side or leave both side as positive as all possible case will give same solution as both of them
Case 1: (x - 2) = (2x-3)
-2+3 = 2x - x
x = 1
or,
Case 2: (x - 2) = -(2x-3)
x+2x = 3+2
3x = 5
x = 5/3
Hopefully this helps

This is correct, we need more information if answer has to be specific value of x
