Question

please help me please​

Answer 1

ANSWER-

$u = \frac{2}{3}$

$v = \frac{ - 5}{6}$

SOLUTION-

3(2u+v)=7uv

6u+3v=7uv......(1)

6u+3v=7uv......×3

18u+9v= 21uv

3u+9v=11uv.....(2)

subtracting (1) and (2)

18u+9v= 21uv......(1)

3u+9v=11uv.....(2)

-...-.....-......

15u = 10

u=10/15

u=2/3

3u+9v=11uv.....(2)

3(2/3)+9v= 11uv

2+9v=11(2/3)v

2+9v=22/3v

2=22/3v-27/3v(27÷3=9)

2=22-27/3v

2= -5/3v

6v=-5

v=-5/6

HOPE THIS HELPED YOU
