算式方法:73+47=120(人)
12/(2+1)=40(人)
73-40=33(人)
方程方法:设派X人过去
2(73-X)=47+X
3X=2*73-47
X=33
答:从第一车间派33人过去。

设派了x人
2(73-x)=47+x
146-2x=47+x
3x=99
x=33
所以一共派了33人

(73+47)/3
=120/3
=40人
派:
73-40=33人

把他们分成三份:(73+47)/3=40
73-40=33人

现在第一车间=(73+47)÷(1+2)=40人
73-40=33人
从第一车间派33人到第二车间

73-(73+47)÷(1+2)=73-40=33人
