Systems of Equations: Elimination







          Skill Practice!




        Use elimination to solve each system of equations.

        1.   x – y = 1                                     6.   x + 4y = –8
             x + y = 3                                          x – 4y = –8












        2.   –x + y = 1                                    7.   3a + 4b = 2
             x + y = 11                                         4a – 4b = 12













        3.   x + 4y  =11                                   8.   3c – d = –1
             x – 6y = 11                                        –3c – d = 5













        4.   –x + 3y = 6                                   9.   2x – 3y = 9
             x + 3y = 18                                        –5x –3y = 30













        5.   3x + 4y = 19                                  10.  x – y = 4
             3x + 6y = 33                                       2x + y  =–4
