4x-5=2x+3
You need to get all the variables (letters, which would be x in this equation) on one side and the numbers on the other.
Adding 5 to both sides:
4x=2x+8
Subtracting 2x from both sides
2x=8
Dividing both sides by 2
x=?
how do you solve |4x-5|=|2x+3|

That correctly provides one possible solution out of two.
Because of the absolute value function, the equation can also be solved as:
(4x-5)=-(2x+3)
which can be transformed to
6x=2, or x=1/3
