.

Let "x" = "how many copies can the old machine produce", i.e. the number under the question.


Then the new machine can produce 2x+5 copies, according to the condition.


You are given


    2x + 5 = 205.


Hence,  2x = 205 - 5 = 200  and  x = 200/2 = 100.


ANSWER.  The old copy machine can produce 100 copies per hour.

Solved.
