Step-by-step explanation:

Eric plays basketball and volleyball for a total of 95 minutes every day.

He plays basketball 25 minutes more than he plays volleyball.

Solving the first equation by substituting x:

Then finding x:

Eric spends 35 minutes on volleyball every day and 60 minutes on basketball

Eric spends 35 minutes on playing volleyball as found above. If he spends 35 minutes on basketball, then we should have:

35 + 35 = 70, which should be 95 minutes

or x = y = 35 which makes the second equation false.

So the answer is NO.
