Can you show me how to find the rectangular equation:

r=2cos(theta) + 3 sin (theta)
All I need is an example to work off I was absent today from Pre-Calc and I have homework to do and no explanation with them-Please help with this one Thank you

sqrt(x^2+y^2) = 2 x/sqrt(x^2+y^2)+3y/sqrt(x^2+y^2)

x^2+y^2 = 2 x + 3 y

y^2 - 3 y = -x^2 + 2 x
Thank you
