Question

Find a system of two equations in three variables x1, x2, and x3, that has the solution set given by the parametric representation x1=t, x2=s and x3=3+s-t, where s and t are any real numbers. Then show that the solutions to your system can also be written as x1=3+s-t, x2=s and x3=t

Answer 1

by x1,x2,and x3 i mean : x sub1 and so on
