Answer:
m17 = 80
m19 = 120
m21 = 100
m23 = 40
Step-by-step explanation:
M17+m21+m23 = 220
M21+m23 = 140
M17+m19 =200
M23+m19 =160
M17+m21+m23 - (M21+m23 ) = 220 - 140
=> M17 = 80
M17+m19 =200
=> 80 + m19 = 200
=> m19 = 120
M23+m19 =160
=> m23 + 120 = 160
=> m23 = 40
M17+m21+m23 = 220
=> 80 + m21 + 40 = 220
=> m21 = 100
m17 = 80
m19 = 120
m21 = 100
m23 = 40
