Find the solution of this system of equations. separate the x- and y-values with a comma. x = -5 + y 28x + 11y = 16

Jorge planted flowers in his garden he planted one row of 12 tulips and one row of 36 daisies george's friend kylie has a garden with 75 flowers in it kylie's garden only contains tulips and daisies. is it possible for kylie‘s garden she have the same ratio of tulips to daisies as george's garden?

What is the solution of the systems of equations? y=2/3x+3 x=-2

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).
