 Practice - Linear Systems - Algebraic Terms of Use    Contact Person: Donna Roberts  Directions: Grab paper and pencil. Solve these system problems algebraically, using either the susbstitution method or the elimination (addition/subtraction) method. Beware!! The Systems Analyst may, or may not, be helpful!

 1. Solve and check this linear system algebraically:         y = x + 7      y = -2x + 1 2. Solve and check this linear system algebraically:         x + 2y = 12      2x - y = 4 3. Solve and check this linear system algebraically:         2a - 2b = 6      5a - 3b = 9 4. Solve and check this linear system algebraically:         13x + 10y = 14          -x + 6y = 4 5.
