Answer 1

Answer:

u = 1/3, v = 1/2

Step-by-step explanation:

11/v - 7/u=1

11u - 7v / uv = 1.

Multiplying whole equation by 6.

66u - 42v / uv = 6 ----------(1)

9/v - 4/u = 6

9u - 4v / uv = 6. ---–-------(2)

Equating equ.1 & 2

66u - 42v / uv = 9u - 4v / uv

66u - 42v = 9u - 4v

57u = 38v

3u = 2v

u = 2v/3 ------(3)

Cutting this value of u in equ. 2

9u - 4v / uv = 6

6v - 4v / uv = 6

2v / uv = 6

2/u = 6

1/u = 3

3/2v = 3

1/2v = 1

2v = 1

v = 1/2

u = 2v/3

= 1/3
