Question

How do you solve `abs(2x - 3 ) = -1`?

Answer 1

This has no solution.

Explanation:

You can see this by knowing what the absolute value actually means: it makes an expression positive. For every expression `f`, it holds that the absolute value is bigger than or equal to `0`:

`|f|>=0`

Since `-1 < 0`, this equation has no solution.
