100 x-5+10 X=5	100 X - 4 = 7 3x= 9	100 2/2 = -26/2 X = -13	100 3m = 21 M = 7
200 M+7=-2 M=-9	200 X - 120 = 80 X = 200	200 2/2 = 1/1 X = 1	200 X = 1200 X/3 = 400
300 x+4=23 x=27	300 Y - 8 = 24 Y = 32	300 5/1 x X/5 = 4.5 X = 20	300 -X/6 = 24 24 = 24
400 y - 8 = 24 y=32	400 -2 + x = 7 X = 9	400 2x/2 = 10/2 X = 5	400 -1/6b = 7 7 = 7
500 X + 3 = 7 x = 4	500 Z- 4 + 4 = 16 + 4 Z = 20	500 D - 5 = 7 D = 12	500 –7k = 18.13 18.13 = 18.13
