At PrintAll copying, a new copying machine can produce five more than twice the number of copies per hour of the old copy machine. If the new machine produces 205 copies per hour, how many copies can he old machine produce?
2x + 5 = 205
x = ______
To find out how many copies the old machine can produce, we need to determine the number of copies produced by the new machine per hour and then apply the given information about the relationship between the two machines.
Let's denote the number of copies produced by the old machine as "x" per hour.
According to the information given, the new machine produces five more than twice the number of copies per hour of the old machine.
So, we can write the equation: 205 = 2x + 5
To solve this equation for x, we need to isolate the variable.
Subtracting 5 from both sides of the equation, we have: 205 - 5 = 2x + 5 - 5
This simplifies to: 200 = 2x
Dividing both sides of the equation by 2, we get: 200 / 2 = 2x / 2
Simplifying further, we find: 100 = x
Therefore, the old machine can produce 100 copies per hour.
