Best ResponseYou've already chosen the best response.0Start by\[X=1Y\] Plug that into the second eqn

Best ResponseYou've already chosen the best response.1ok but htne there aren't any values for the the other equations do I'm suiming it has to be a negative number. someone told me for a similar problem with one negative answer and one positive answer I could add both equations and then muliplty the result and substitute it for either varible to find the other. it worked for that problem but not for this one wwhere both answers are positive

Best ResponseYou've already chosen the best response.0well if it is like how @incomplte said then i have the answer but if it is like how you are saying then i dont know

Best ResponseYou've already chosen the best response.0Just start by Solving for X So from X+Y=1, say X=1Y then plug that into the second equation.

bleumom22

Best ResponseYou've already chosen the best response.1oooh. ok and then just input the answer for one of the variables then divide the varible by its self and the answer by its self to get the variable's value?

Best ResponseYou've already chosen the best response.1as one of the varibles* to reverse calculate?
