Asystem of equations is shown below: equation a: 4c = d − 8 equation b: c = 5d + 8 which of the following steps should be performed to eliminate variable d first? a. multiply equation b by 4 b. multiply equation a by -5 c. multiply equation a by 4 d. multiply equation b by 5

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?
