Question

Find a parametric representation of the solution set of the linear equation. (Enter your answer as a comma-separated list of equations. Use s and t as your parameters.)
x + y + z = 8

Answer 1

Answer:

  x = s, y = t, z = 8 -s -t

Step-by-step explanation:

It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.

You could get more elaborate if you want:

  x = 4-s, y = 4-t, z = s+t
