Question

help with all of the questions?

Answer 1

1. x + 3y = 3 and x - 2y = 0
2. (2,1)
3. solution
4. true
5.  equation 1 :                        equation 2 :
     x + y = 3                                x - 2y = 0
     2 + 1 = 3                                2 - 2(1) = 0
     3 = 3 (correct)                        2 - 2 = 0
                                                   0 = 0 (correct)

both equations are true...so (2,1) is a solution set to this system of equations
