Answer 2

Answer:

u = 1, v = 1.5

Step-by-step explanation:

3(2u + v) = 7uv

=> 6u + 3v = 7uv ---- Eq 1

3(u + 3v) = 11uv

=> 3u + 9v = 11uv ---- Eq 2

Multiplying Eq 1 by 3,

18u + 9v = 21uv ----- Eq 3

Eq 3 - Eq 2,

18u + 9v = 21uv

3u + 9v = 11uv

15u = 10uv

=> v = 15u / 10u = 1.5

Substituting v=1.5 in Eq 1

6u + (3*1.5) = 7u(1.5)

=> 6u + 4.5 = 10.5u

=> 4.5u = 4.5

=> u = 1
