My textbook says this "The solution set in the prior example is parametrized with y and w.
But the prior example solution set had:
{(2-2z+2w, -1 + z - w, z,w) | z,w E R }
The E means element of.
The R is the set of real numbers.
So I was confused by the textbook. Doesn't the book mean the solution set in the "current" example which has:
{(y,y,2-3w,w) | y ,w E R}
To me, the first solution set I post would be parametrized by z and w
The second solution set would be parametrized by y and w.
Am I not correct about those being the right parameters for the solution set?
