Question

Solve it for me ... I will be thankful

Answer 1

6u+3v=7uv .... (1)
3u+9v=11uv .... (2)
multiply (1) by 3 we get
18u+9v=21uv ... (3)
subtract(2) from (3) we get
15u=10uv
v=15u/10u
v=3/2

Answer 2

Hi ,

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

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

Multiply equation ( 2 ) with 2 we get,

6u + 18v = 22uv ----( 3 )

Sutract equation ( 1 ) from

equation ( 2 ), we get ,

15v = 15uv

15v / 15v = u

1 = u

u = 1

Put u = 1 in equation ( 1 ) , we get

6 + 3v = 7v

3v - 7v = - 6

- 4v = -6

v = ( -6 ) / ( - 4 )

v = 3/2

Therefore ,

u = 1 , v = 3/2

I hope this helps you.
