ALGEBRA 1

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

    2x-3y    4

solution

x+3y = 1           

2x-3y   4

1(2x-3y) = 4(x+3y)           [after cross multiplying]

2x-3y = 4x+12y

2x - 4x = 12y + 3y

-2x = 15y

¹-2x = ^-7.515y

₁-2          -2 ₁

 x = -7.5y

     

x = -7.5y

y       y

x = -7.5

y    

Hence ^x/_y = -7.5  answer.
