# Matrix transformations of curves watch

1. Hi, working through one of TeeEm's worksheets and I couldn't do this question correctly. http://www.madasmaths.com/archive/ma...ons_part_a.pdf No.38

Anyway, as the curve is the transformed one, you want to form equations for the values of X and Y of the transformed curve

hence X=2x-y and Y=2x-3y where the equation of the curve is 13X^2-16XY+5Y^2+8X-6Y=4

Substituting these values in and algebra bashing doesn't give me the correct answer, what am I doing wrong?
2. Y=3x+2y
X=2x+y
