3. In each of the following systems, interpret each
equation as a line in the plane. For each system,
graph the lines and determine geometrically the
number of solutions.
(a) x₁ + x₂ = 4
x₁ - x₂ = 2
2x₁ - x₂ = 3
-4x1 + 2x₂ = -6
(c)
(b)
X₂ = 3 (d)
x₁ + 2x₂ = 4
-2x₁ = 4x₂ = 4
x₁ + x₂ = 1
-
x₁ - x₂ = 1
-x₁ + 3x₂ = 3
