How can we determine the intersection point of two lines with given equations?

Yep, now apply the methods of checking I mentioned above. (Nod)

im actually not getting the same answers. i think i made a mistake.

t=2

it does satisfy the third equation as well. so now i plug in s and t into the parametric equations and and get x,y,z which turns out to be (4,-1,-5) and i checked with the back of the book. it's right :)
