Best ResponseYou've already chosen the best response.0Just use logic. Test out numbers and see which ones fit.

Best ResponseYou've already chosen the best response.0ya I was going to do that but I its not multiple choice and I'm not sure how to use matrices to solve the problem...

Best ResponseYou've already chosen the best response.0It doesn't need to be multiple choice. I already figured out what x, y, and z are just by using logic.

Best ResponseYou've already chosen the best response.0I'll give you a couple of tips. In the second line, you notice that 4x and 5y added only get 3, so that means either x or y is negative. In the third line, you notice that y minus3 times z is 10 so that means y is a small number and z is definitely positive.

Best ResponseYou've already chosen the best response.0you can multiply the first equation by \(4\) and add it to the second that will eliminate the \(x\) terms, then you will be left with two equations and two unknowns

Best ResponseYou've already chosen the best response.0\[4x4y4z=16\\ 4x+5y=3\] add and get oh i see are you supposed to row reduce the matrix? it is really the same thing exactly
