Question

solve this Plz the question is in the photo 2/^x +3/^y =4/^x -9/^y = -1

Answer 1

Let 1/root x be a and 1/root y be b
∴ 2a + 3b =-1 and 4a - 9b =-1
 solving both,
By elemination method we have,
 4a - 9b = -1
 4a + 6b = -2
------------------
-15b = 1
⇒b = -1/15

putting b in any one equation we get,
a = -2/5

∵ 1/root x = a 
∴ x = - root 5/2

and 1/root y = b
∴ y = - root 15
