1x = 12 - 13

1x = -1 (divide both sides by 1 to get x)

1x/1 = -1/1

x = -1

| x+13=11 | | x+13=10 | | x+13=9 | | x+13=8 | | x+13=7 | | x+13=6 | | x+13=5 | | x+13=4 | | x+13=3 | | x+13=2 | | x+13=1 | | x+12=20 | | x+12=19 | | x+12=18 | | x+12=17 | | x+12=16 | | x+12=15 | | x+12=14 | | x+12=13 | | x+12=12 | | x+12=11 | | x+12=10 | | x+12=9 | | x+12=8 | | x+12=7 | | x+12=6 | | x+12=5 | | x+12=4 | | x+12=3 | | x+12=2 | | x+12=1 | | x+11=20 |
