Answer 2

To simplify the expression (36y/x - 25x/y)/(6y - 5x), we can start by multiplying the numerator and denominator by the least common multiple of x and y, which is xy:

(36y/x - 25x/y)/(6y - 5x) * (xy/xy)

Simplifying the expression in the numerator using the distributive property:

= [(36y^2 - 25x^2) / (xy)] / (6y - 5x)

We can factor the numerator using the difference of squares:

= [(6y + 5x)(6y - 5x) / (xy)] / (6y - 5x)

The (6y - 5x) in the numerator and denominator cancel out, leaving:

= (6y + 5x) / xy

Therefore, the simplified expression is (6y + 5x) / xy.

So, (36y/x - 25x/y)/(6y - 5x) = (6y + 5x) / xy

Now, to find the value of the expression when x = 3 and y = 4, we simply substitute those values in:

(6(4) + 5(3)) / (3)(4) = 39/12 = 3.25

Therefore, when x = 3 and y = 4, the value of the expression is 3.25.
