Question

2 + V5; 9 + 4√5; 38 + 17√15; ​

Answer 1

Answer:

The answer is u = 5 , v =1/7

Step By Step Explanation :

15/u + 2/v = 17 ---( 1)

1/u +1/v= 36/5-( 2)

multiply equation (2) with 2, we get

2/u +2v= 72/5-(3)

subtract equation ( 3) from equation (1)

15/u - 2/u = 17 - 72/5

13/u = (85- 72 V5

we get

1/u = 13/ (5x 13)

u =5(4)

substituteu=5 in equation (1), we get

13/u 13/5

1/u = 1/5

15/5 +2/v = 17

3+2/v= 17

2/v =17- 3

2/v 14

v/2 1/14

2/v 14

V=2/14

V 1/7

:. u =5,v= 1/7
