Guys how can l find the parametic representation for the curve :
$\displaystyle x^2+y+z=2$ and $\displaystyle xy+z$
I tried to make z=t and solve simultaneous equations but that route did not take me anywhere.
In particular, you have one equation and the expression "xy+z" not equal to anything. I think you have two equations representing surfaces and want parametric equations for the curve where they intersect- but you did not actually say that and one of the equations is incomplete.
