Question

What is the solution set for `-2m + 5 = -2m - 5`?

Answer 1

`x = O/`

Explanation:

This equation has no real solutions.

You can cancel out the two `m`-terms to get

`color(red)(cancel(color(black)(-2m))) + 5 = color(red)(cancel(color(black)(-2m))) - 5`

This will leave you with

`5 !=-5`

As it is written, this equation will always produce the same result, regardless of value `x` takes.
