The machines represent equivalent expressions.
The output produced by both machines is 372
The equation represented on machine A is:

The equation represented on machine B is:

Where: x and y represent the inputs and the outputs, respectively
When the outputs are the same, it means:

So, we have:

Open brackets


Collect like terms


Divide both sides by 2

Substitute 39 for x in 


Hence, the output produced by both machines is 372
