Best ResponseYou've already chosen the best response.3here's an easy one: 2x + y = 3 x + y = 1

Best ResponseYou've already chosen the best response.22x + y = 3 + x + y = 1 Is this the right first step?

Best ResponseYou've already chosen the best response.3you can do 3 different things to solve a linear system: 1. graph the equations, and find where they intersect. 2. substitution 3. elimination.

Best ResponseYou've already chosen the best response.3you can; in fact elimination would be the easy way out of this one

Best ResponseYou've already chosen the best response.2Can i divide the equations?

Best ResponseYou've already chosen the best response.3if you subtract equation 2 from equation 1: you get x = 2 x + y = 1 next step is to subtract the new equation 1 from equation 2

Best ResponseYou've already chosen the best response.3you can't really divide the equations

Best ResponseYou've already chosen the best response.2Give me another one so i can try, i think i see the pattern

Best ResponseYou've already chosen the best response.32x + y = 5 x + y = 3

Best ResponseYou've already chosen the best response.22x + y = 5  x + y = 3 = x=2? The y's cancel out right?

Best ResponseYou've already chosen the best response.2Now i can substitute to get y

Best ResponseYou've already chosen the best response.2I can cross check this with the other equation
