== Consider the DE x = y + x - y with $x > 0. sing Moving to another question will save this response. other question will save this response. x/12 = y + /x y with $x > 0.U sing nother question will save this response. hence the DE reduced to and the general solution is: xdu + udx du/sqrt {1-u^{2}} = dx/3 sin^{-1}u = ln|cx| e^ {sin^{-1}(y/x)} = cx
