Answers
Steve
k+y = 500
k+m = y+220
y+m = k+140
Or, in more standard format,
k+m = 500
k+m-y = 220
-k+m+y = 140
These are easy to solve.
k+m = y+220
y+m = k+140
Or, in more standard format,
k+m = 500
k+m-y = 220
-k+m+y = 140
These are easy to solve.

Thx. For the answer now I am finished with math homework.
Ssseeeesßss
K+M=220+Y
Y+M=140+K
220+140=360
2M=360
M=360÷2=180
M=180
Y+M=140+K
220+140=360
2M=360
M=360÷2=180
M=180
