Idont understand what i'm supposed to do

Your suppose to take the order pair you got and subsitute it in both of the equations. The chart has the y and x on one side and a number on the other. Treat it like an algebraic equation and try to see if when you subsitute the x and y with the order pair given you get the number on the other side of the equation. For example x + 3y = 6 once subsituted with the order pair looks like 3 + 3(1) = 6. From there you do one step at time until finally you get 6 = 6 which tells you that (3,1) is a solution for this equation. Now you have to find out if the ordered pair works for both of the equations not just one since it said "given system". Hope I explained it clearly enough :)  

if i put something wrong your not gonna like it so rather not say nothing.
