Best ResponseYou've already chosen the best response.1you can sub in your points into each equation and if the equations come out true (both of them), then it is a solution. Understand ?

Best ResponseYou've already chosen the best response.1Let me set up the first equation... 3x + 2y = 21 (x = 5 and y = 3) 3(5) + 2(3) = 21 now work that out and tell me if it is true.

Best ResponseYou've already chosen the best response.1do the same for the other equation... x  y = 2 5  (3) = 2 Is that true ? If they are BOTH true, then those points are a solution, But if even 1 of them is false, then it is not a solution

Best ResponseYou've already chosen the best response.13x + 2y = 21 3(5) + 2(3) = 21 15  6 = 21 21 = 21 (true) x  y = 2 5  (3) = 2 5 + 3 = 2 2 = 2 (true) so if they are both true, which they are, then the solution is true and (5,3) are points that satisfy this set of equations :)
