Folks, Could anyone check my attached work. Mathematica seems to output u(x,y)=-3+2x for the particular solution... Thanks

If we parametrize x and y we have and Then Now if we take the derivative with respect to s we have This gives the system of equations Solving this gives Now if we sub out we get
Here's your mistake First let so . If then so so (your Mathematica and TheEmptySet's solution)
Cheers Danny! I like this alternative method, TheEmptySet. Thanks
