22%2B6x=28%2B4x for x hours of usage


3 hours, they would be equal cost.



----------------
A little more detail


--------------------------------------------------------------------
company A will rent the machine you need for $22 plus $6 per hour.
-------------------------------------------------------------------
If cost is A, then description is simple linear equation A=6x%2B22.


-----------------------------------------------------------------------
Company B will rent the same machine for $28 plus $4 dollars per hour.
------------------------------------------------------------------------
If cost is B, then rent will cost B=4x%2B28, as a simple linear equation.

For how many hours, x, will both A and B be the same?
A=B
6x%2B22=4x%2B28
6x-4x=28-22
2x=6
