To solve the equations by the method of substitution: (1) 1 / x + 1 / y = 5, (2) 1 / xy = 6 Hurry!

To solve the equations by the method of substitution: (1) 1 / x + 1 / y = 5, (2) 1 / xy = 6 Hurry!

Let 1 / x = m, 1 / y = n
m+n=5
m*n=6
M = 3, n = 2 or M = 2, n = 3
X = 1 / 3, y = 1 / 2 or, x = 1 / 2, y = 1 / 3
