Solve the system of linear equations using the elimination method: 2x + 2y = 16 -2x +3y = 14

Step-by-step explanation:

soulution:

        given,              2x +2x = 16 - 2x + 3y = 14

                                 2x + 2x = -2y +3y = 14 -16

                                       4x = y = -2

                                         y = 4x = -2

                                          y = x =  4/-2

                                         x = y = -2 ans
