x+100=y,z+200=x,3x+3y+6z=50236求解x+100=y,z+200=x,3x+3y+6z=50236求解x+100=y,z+200=x,3x+3y+6z=50236求解x+10

x+100=y,z+200=x,3x+3y+6z=50236求解
x+100=y,z+200=x,3x+3y+6z=50236求解

x+100=y,z+200=x,3x+3y+6z=50236求解
x+100=y,--------------(1)
z+200=x,--------------(2)
3x+3y+6z=50236--------(3)
由(1),(2)得:y=100+x=300+z,代入(3)得:
3(z+200)+3(300+z)+6z=50236,
12z=50236-1500=48736
z=4061又1/3,
x=4261又1/3,
y=4361又1/3.

y=x+100
z=x-200
代入3x+3y+6z=50236
3x+3(x+100)+6(x-200)=50236
3x+3x+300+6x-1200=50236
12x=51136
x=12784/3
y=x+100=13084/3
z=x-200=12184/3
