Question
If 5x - 13xy + 6y = 0, find x :
y.Solution
We'll simplify 5xΒ² - 13xy + 6y2 = 0, by splitting the xy term 5x2 -10xy - 3xy + 6y2 = 0 = 5x (x-2y) - 3y (x-2y) = 0 = (5x-3y) (x β 2y) = 0 Taking, β 5x - 3y = 0 β 5x = 3y Β β x: y = 3:5 Taking, β x - 2y = 0 Β β x = 2y β x: y = 2:1 Finally x:y =3:5 or 2:1
