Best ResponseYou've already chosen the best response.02x + y = 3 + x + y = 1 Is this the right first step?

Best ResponseYou've already chosen the best response.0you 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.0Can i divide the equations?

Best ResponseYou've already chosen the best response.0if 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.02x + y = 5  x + y = 3 = x=2? The y's cancel out right?
