## Homework Statement

Find cartesian equations of the line of intersection of the planes x+3y-6z =2 and 2x+7y-3z=7

## The Attempt at a Solution

What I did first was I cross product the 2 equation and then I got 33i-9j+k

Then I took both of the equation and let y = 0. After that my answer seems to be weird.. Did I did anything wrong? The answer of the book was given ∴x+7/33 = y-3/-9 = z
