ALGEBRA 1

If  x+5y = 1            find  ^x/y             

    x-3y     4

solution

x+5y = 1           

x-3y     4

1(x-3y) = 4(x+5y)           [after cross multiplying]

x-3y = 4x+20y

x - 4x = 20y + 3y

-3x = 23y

¹-3x = 23y

₁-3      -3

 x = -23y/3

x/y = -23/3

x = 5y

     

x = 5y

y     y

x = 5

y    

Hence ^x/_y = 5  answer.

If  x+2y = 1            find  ^x/y             

    x- 2y     5
