    Part 1: It means that the system of equations is always true regardless of what values the unknown variables take. Thus, you get infinite number of solutions for that system Part 2: Add the two equaions: 3y - 2x + y+ 2x = 11 + 9 => 4y = 20 => y = 5 Substituting in second equation, 5 + 2x = 9 => 2x = -4 => x = -2 So, (x,y) = (-2,5)
