w+2x=16 ⇒ w=16-2x


x+2w=14        x+2(16-2x)=14

                      x+32-4x=14

                     -3x=14-32

                      -3x=-18  /:(-3)

                       x=6


w=16-2x=16-2·6=16-12=4


2y+w=-6 ⇒   2y+4=-6

                   2y=-6-4

                   2y=-10  /:2

                   y=-5
