Find parametric equations and symmetric equations for the line of intersection of the given planes.
x + y + z = 2, x + z = 0

X=1
y =
Z=
x=, y=

  • Math -

    let z = t
    then x+t = 0
    x = -t

    into the firs
    -t + y +t = 2
    y = 2

    so
    x = -t
    y = 2
    z = t for parametric

    t = x/-1
    t = z

    symmetric:
    x/-1 = z, y = 2
