Answer 2

Just change the 'a' value now.

${\huge{\frac{a}{3-18}}}$ = ${\huge{\frac{1}{-30}}}$

${\huge{\frac{a}{-15}}}$ = ${\huge{\frac{1}{-30}}}$

Therefore, a = ${\huge{\frac{1}{2}}}$

Now,

a = ${\huge{\frac{1}{\sqrt{x}}}}$

Therefore,

${\huge{\frac{1}{2}}}$ = ${\huge{\frac{1}{\sqrt{x}}}}$

==> ${\sqrt{x}}$ = 2

==> x = 4


Therefore, x = 4 ; y = 9
