I'm trying to study Euclidean spaces and one of the exercises is to derive the nonparametric equation for the following plane:
x = 2 - 3s + t
y = 4
z = 1 + s + t
I tried to write a new equation expressed in terms of x and y only:-
t = x - 2 + 3s = z -1 - s
However, I was stuck because I couldn't solve for s and t.
The textbook lists answer y=4 as the answer. Why? Please help me understand! Thank you!
