Question

Solve the following system of linear equations
45/u+7/v =10 ,15/u+14/v=5​

Answer 1

Step-by-step explanation:

let 1/u=x

1/v=y

45x+7y=10. ---(1)

15x+14y=5. ---(2)

eqn (2) multiply 3 and subtract eqn (1)

45x+42y=15

45x+7y = 5

---------------------

35y=10

y=10/35

y=2/7

y=1/v=7/2

'y' value substitute in eqn (1)

45x+7(2/7)=10

45x+2=10

45x=8

x=8/45

x=1/u=45/8

Answer 2

Step-by-step explanation:

Ans is u=5 and v=7.........
