(500-m)+200=600 m=
m-(100+300)=500 m=
600-(m-100)=300 m=

Answer 1

1 ) 500 - m = 600 - 200 = > 500 - m = 400 = > m = 500 - 400 = > m = 100
 2 ) m - 400 = 500 = > m = 500 + 400 = > m = 900
 3 ) m - 100 = 600 - 300 = > m - 100 = 300 = > m = 300 + 100 = > m = 400

Answer 2

$a).(500-m)+200=600 \\ 500-m=600-200 \\ 500-m=400 \\ -m=400-500 \\ -m=-100 \\ m=100 \\ b).m-(100+300)=500 \\ m-400=500 \\ m=500+400 \\ m=900 \\ c).600-(m-100)=300 \\ 600-m+100=300 \\ -m=300-600-100 \\ -m=-400 \\ m=400$
