3x-y=-1 and 2x+y=-14 how to solve showing work?

Sagot :

Panoyinidn
3x -  y = -1   ⇒ 6x - 3y = -2
2x + y = -14 ⇒ 6x + 2y = -42
                               -5y = 40
                                -5     -5
                                  y = -8
                       3x - (-8) = -1
                         3x + 8 = -1
                                -8    -8
                              3x = -9
                               3      3
                                x = -3
                          (x, y) = (-3, -8)
