The solution set of a linear system involving variables x1,...,xn is a lists of numbers (s1,...,sn) that makes each equation in the system a true statement when the values s1,...,sn are substituted for x1,...,xn respectively.
I say it is true because I thought the list meant each solution corresponding the variables is true and so if you plug it in for each one respectively, it should be true.
The Key says it is wrong and it gives a explanation that I don't think it's even English
False. The description given applied to a single solution. The solution set consists of all possible solutions. Only in special cases does the solution set consist of exactly one solution. Mark a statement True only if the statement is always true.
