Algebra 2 Worksheet Solving Matrix Equations Name________________________ Date______________ You may use your calculator for the final answers but you must SHOW the initial work including naming each matrix and showing what you are entering in the calculator. (For #1 you should write AX+B=C-1 then show the steps to solve the equation with the matrix names listed but use your calculator to do the matrix arithmetic. Be careful as to whether you are going to PRE or POST multiply when you use the inverse to solve. When I solve B+AX =C, I use AX=C-B then X=A-1(C-B) but I enter each matrix A,B,C in my calculator and let it produce the answer.) 1. 5 3O L 1 1OL 2 3O L X M P M P M P 2 0Q N 1 1QN 4 1Q N 2. 1 0O L2 1OL 0 1O L XM M P M P P 0 1Q N 2 10 QN 1 1Q N 3. 2 1 L M 4 1 M M 0 2 N 1 O P P P Q L M M M N O P P P Q 0 1 1 1 1 X 2 1 3 2 0 1 3 Algebra 2 Worksheet Solving Matrix Equations Name________________________ Date______________ 4.
