Solution

Solution

The numbers : \frac{51 + 2229}{12}, \frac{51 - 2229}{6}, \frac{2229 - 153}{12} + 19

Solution steps

Represent the numbers with

x, y, z

number 1 : x

number 2 : y

number 3 : z

A.T.Q.:

x + y + z = 19

2 x + 3 y + 4 z = 59

6 x y = 31

Solve the system of equations:

x + y + z = 19, 2 x + 3 y + 4 z = 59, 6 x y = 31 : (x = \frac{51 + 2229}{12}, y = \frac{51 - 2229}{6}, z = \frac{2229 - 153}{12} + 19)

The numbers : \frac{51 + 2229}{12}, \frac{51 - 2229}{6}, \frac{2229 - 153}{12} + 19
