Question

If x+3y upon 5x+4y= 1/3 find the ratio of x:y ANSWER FASTTT

Answer 1

x/y = 5/2

Explanation:

hello :

(x+3y) /( 5x+4y)= 1/3 means : 5x+4y = 3(x+3y)

5x+4y = 3x+9y

5x-3x = 9y - 4y

2x = 5y

now divid by y : 2x/y = 5y/y

2x/y = 5 so : x/y = 5/2

Answer 2

x : y = 5 : 2

Explanation:

Given

`(x+3y)/(5x+4y)` =
`(1)/(3)` ( cross- multiply )

5x + 4y = 3(x + 3y)

5x + 4y = 3x + 9y ( subtract 3x from both sides )

2x + 4y = 9y ( subtract 4y from both sides )

2x = 5y ( divide both sides by 2 )

x =
`(5)/(2)` y ( divide both sides by y )

`(x)/(y)` =
`(5)/(2)` , that is

x : y = 5 : 2
