Question

. x / 7= y / 3 = (3x+5y) / (_____) *​

Answer 1

Step-by-step explanation:

x/7=y/3=(3x+5y)/A.=(7x-9y)/B

X/7=y/3

=> 3x = 7y

=> 3x + 5y = 7y + 5y = 12y

=> y/3 = 12y/ A

=> A = 12 * 3

=> A = 36

7x-9y

= 7(7y/3) - 9y

= (49y - 27y)/3

= 22y/3

=> y/3 = 22y/ 3B

=> B = 22

x/7=y/3=(3x+5y)/36
