Answer 2

Explanation:

z/m - z/n = 1 Take out z as a common factor.

z (1/m - 1/n) = 1 Find the common denominator of the 2 fractions

m * n is the common denominator. Multiply the two fractions by mn

z (n - m)/mn = 1 Multiply by mn

z (n - m) = mn Divide by n - m

z = mn/(n - m)

The last line is your answer.
