If  x+3y = 1            find  ^x/y             

    5x-3y    3

 

Solution

 

x+3y = 1           

5x-3y   3

 

1(5x-3y) = 3(x+3y)           [after cross multiplying]

 

5x-3y = 3x+9y

 

5x - 3x = 9y + 3y   [after collecting the like terms]

 

2x = 12y

 

¹2x = ⁶12y

₁2        2 ₁

 

 x = 6y

     

x = 6y

y      y

 

x = 6

y    

 

Hence ^x/_y = 6  answer.
