  2. Subtract Eq2 from Eq1:
    Diff. = 3y + 2z = 3.
    Add Eq2 and Eq3:
    Sum = 2y + 4z = 2.

    3y + 2z = 3. Multiply by 2 and subtract.
    2y + 4z = 2.

    6y + 4z = 6.
    2y + 4z = 2.
    Diff. : 4y = 4.
    Y = 1.
    6y + 4z = 6,
    6*1 + 4z = 6,
    Z = 0.

    Eq1: -2x + 2y + 3z = 0.
    -2x + 2*1 + 3*0 = 0,
    X = 1.

    Solution = (x, y, z) = (1, 1, 0).
