### can anyone help me solve this problem?

I'm newbie with sage program and to solve diff(y,x) == (4 * x + y)^2 with it i typed like below

var('x') y = function('y')(x) de = diff(y, x) == (4*x + y)^2 desolve(de, [y, x])

But it is not working I know i should use substitution that u = 4 * x + y but i don't know how to do it with sage Can anyone help me?
