Write a matrix representing the system of equations.
X+2y+z=5
2x-y+2z=15
3x+y-z=8
Solve the System by transforming your matrix into reduced row echelon form. State the solution as an ordered triple.
sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
