ALGEBRA 6

If  x+6y = 1            find  ^x/y             

    x-3y     4

solution

x+6y = 1            

x-3y    4

1(x-3y) = 4(x+6y)           [after cross multiplying]

x-3y = 4x+24y

x - 4x = 24y + 3y

-3x = 27y

¹-3x = 27y

₁-3      -3

 x = -27y/3

x/y = -9           [after dividing by y on both sides]

x = -9

y    

Hence ^x/_y = -9  answer.
