Step-by-step explanation:
x =7y ----(1)
xy=252 ----(2)
(1) into (2):
(7y)(y) = 252
![7 {y}^{2} = 252 \\ 7y = \sqrt{252}](https://tex.z-dn.net/?f=7%20%7By%7D%5E%7B2%7D%20%20%3D%20252%20%5C%5C%207y%20%3D%20%20%5Csqrt%7B252%7D%20)
7y=15.874....
y=2.27
y value into (1)
x= 7(2.268)
x=15.87
the two numbers are 15.87 and 2.27 (Ans)
