For each system of linear algebraic equations, determine if the system is underdetermined, has a unique solution, or is overdetermined. If the system is underdetermined find the general solution and then choose a particular solution and check your answer. If the system has a unique solution, find the unique solution and check your answer. If the system is overdetermined, find a least squares solution.

a. x1 2x2 + 3x3 5 x1 x2+X3 1 x1-2x2-3x,--2 b. x1 + 2x2 + 3x3-5 -2x1-4x2-6x3??10 x1-2x2-3x3?-2 ?. x1 + 2x2 + 3x3 = 5 x1 + x2 X3 1 2x1 + 2x2 + 2x3-.3
