Question

Af2x+7y: 5x+3y= 11:13, y/x = ?
(a) 2
(b) 1/2
(c)3
(d) 1/3​

Answer 1

Answer:

(b) 1/2

Step-by-step explanation:

2x+7y : 5x+3y = 11 :13

=> (2x+7y) / ( 5x+3y) = 11/13

=> 13( 2x+7y) = 11 ( 5x+3y)

=> 26x -55x = 33y- 91y

=> - 29x= - 58y

=> y/x= -29/-58= 1/2

option (b) is correct => 1/2
