Question

If 3x +4y: x+2y =9/4 then 3x+5y: 3x-y=

Answer 1

Answer:

7

Step-by-step explanation:

3x + 4y : x + 2y = 9/4

=> 3x+4y/x+2y = 9/4

=> 4( 3x+4y) = 9( x+2y)

=> 12x+16y = 9x+18y

=> 12x-9x = 18y-16y

=> 3x = 2y

=> x = 2y/3

Now, 3x+5y: 3x-y = ? ------------------(1)

putting the value of 'x' in (1)

3(2y/3)+5y/3(2y/3)

=> 2y+5y/ 2y-y

=> 7y/y

=> 7
