Question

解三元一次方程组（急需,
x:y=5:3
x:z=7:3
2x-y-z=35
5x+6y+2z=80
4-3y+z=16
3-2y+6z=93
x+2y=4
2x+3z=13
3y+z=6
x:y=5:3
x:z=7:2
x-2y+3z=46
x+y+z=15
2+3y-z=9
5x-4y-z=0
3x-4y+5z=18
2x+y-6z=8
x+3y+z=22

Answer 1

x=1225/34 y=735/34 z=525/34
x=-77/5 y=33/2 z=41/2
x=2 y=1 z=3
x=70 y=42 z=20
x=14/3 y=117/27 z=6
x=8 y=4 z=2
刚刚算出来,可能存在少数错误
