**Simple algebra question**

## Homework Statement

In a biology class of s students, there are m microscopes available. if the instructor assigns one micrope to each student, 6 more microscopes will be needed. If the instructor had twice as many microscopes available and assigned one microscope to each student, 6 microscopes would be left over. What is the value of s?

## Homework Equations

## The Attempt at a Solution

I solved for s by "guess + check". I tried expressing the word problem algebraically, but I can't seem to get it right. I get a negative instead of a positive value, so I find the absolute value and end up with the final results. Yet, I'm sure there is another way out.

Here are my equations:

sm=m-6

Hence, s= (-6/m)

Second equation,

2ms=m+6

Then I do substitution and get -18??!

Also, my equations don't really illustrate what is described above.
