Question

√x + y = 25 and √y + x = 16 find x and y

Answer 1

Step-by-step explanation:

$( \sqrt{x} + y = 25 ) \times x= x + xy = 25x$

$( \sqrt{y} + x = 16) \times y = y + xy = 16y$

x + xy = 25x

(-)y + xy = 16y

------------------------

x - y = 25x - 16y

16y - y = 25x - x

15y = 24x

x/y = 24/15

$\frac{x}{y} = 8 : 5$
