Given the equation 2f(x) + xf(1/x) = x, we can substitute x = 10 to find f(10).

So, we have:

2f(10) + 10f(1/10) = 10

Now, we need to find f(1/10) by substituting x = 1/10 into the equation:

2f(1/10) + (1/10)f(10) = 1/10

Now we have two equations:

1) 2f(10) + 10f(1/10) = 10
2) 2f(1/10) + (1/10)f(10) = 1/10

Solving these equations simultaneously will give us the value of f(10).
