解方程，请各位大神帮帮忙！！

x/3+y/4+(3200-x-y)/5=3200-2400

x/5+y/4+(3200-x-y)/3=3200-2320

Answer 1

x/3+y/4+(3200-x-y)/5=3200-2400，
x/3+y/4+640-x/5-y/5=800，
2x/15+y/20=160,①
x/5+y/4+(3200-x-y)/3=3200-2320，
x/5+y/4+3200/3-x/3-y/3=900,
2x/15+y/12=500/3.②
②-①，得y/30=20/3,y=200,
代入①，得2x/15=150,x=1125.
所以{x=1125,
........{y=200.

Answer 2

y=50360
x=39365
