hehehehehehe solution to 22 i): u = 3x/4 ,v=5y/4. make x and y the focus of each expression, as now x and y can be expressed as 2cos(bla) and 2sin(bla) respectively and divide both sides of each equation by two. now use the identity the cos^2(bla) + sin^2(bla) = 1 and sub the other value so u have the equation.
