Question

15/u+2/v = 17
1/u - 1/v = 36/5
using elimination mathod plz as soon as possible

Answer 1

Answer:

1/u= 1/5 and 1/v= 7

Step-by-step explanation:

Let 1/u be a

and 1/v be b

Then 15a+2b=17......(1)

a + b= 36/5......(2)

Multiply (2) by 2

15a+2b=17......(3)

2a+2b=72/5.....(4)

Subtract (4) from(3)

13a=17-72/5

13a= 85-72

5

65a=13

a=1/5

Putting the value of a in eq. (2), we get

1+5b/5= 36/5

1 +5b=36

5b=35

b=7

HOPE THIS HELPS!!
