Find all solutions by transforming the system to reduced echelon form and back substituting. (if there are an infinite number of solutions use s1 as your parameter. if there is no solution, enter no solution.)
2x1 + x2 = 2
−x1 − x2 − x3 = 4

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
