Question

solve for X and Y using substitution method , √7x+√13y=0 , √5X +√17Y=6
​

Answer 1

Answer:

The result is 5.34

Step-by-step explanation:

$\sqrt{7} x + \sqrt{13} y=0$ ---------(1)

$\sqrt{5}x +\sqrt{17}y=6$ ----------(2)

From (1) we get,

$x=-\frac{\sqrt{13}y }{\sqrt{7} }$

By putting the value of x into equation no. (2) we get,

$\sqrt{5} (-\frac{\sqrt{13}y }{\sqrt{7} } )+\sqrt{7} y=6$

$-\frac{8y}{\sqrt{7} }+\sqrt{17}y=6$

$-3y+\sqrt{17}y=6$

$y(\sqrt{17}-3)=6$

$y=\frac{6}{\sqrt{17}-3 }$

$y=5.34$
