To simplify the expression, we need to combine the fractions and solve for y.

Starting with the given expression:

2y/y - 5 = 5/y - 5

Simplify the left side by canceling out the y in the numerator and denominator:

2 - 5 = 5/y - 5

Combine like terms on the left side:

-3 = 5/y - 5

Now, add 5 to both sides:

-3 + 5 = 5/y

2 = 5/y

Multiply both sides by y:

2y = 5

Finally, divide by 2 to solve for y:

y = 5/2

Therefore, the solution is y = 5/2.
