Componendo and Dividendo in finding the ratio

If 7x - 15y = 4x + y , find the value of x: y . Hence, use componendo and dividendo to find the values of : (i) (9x + 5y)/(9x - 5y) (iI) (3x^(2) + 2y^(2))/(3x^(2) - 2y^(2))

Using componendo and dividendo, find the value of x if (sqrt(3x+4)+sqrt(3x-5))/(sqrt(3x+4)-sqrt(3x-5))=9 .

Show that for a wave travelling on a string y_(max)/v_(max)=v_(max)/a_(max) wher the symbols have usual meanings. Can we use componendo and dividendo taught in algebra to write (y_(max)+v_(max))/(y_(max)-v_(max))=(v_(max)+a_(max))/(v_(max)-a_(max))?
