解方程组X+Y除以2+X—Y除以3=6和4(X+Y)—5(X—Y)=2(X+Y)除以2+(X—Y)除以3=6和4(X+Y)—5(X—Y)=2
解方程组X+Y除以2+X—Y除以3=6和4(X+Y)—5(X—Y)=2
(X+Y)除以2+(X—Y)除以3=6和4(X+Y)—5(X—Y)=2

解方程组X+Y除以2+X—Y除以3=6和4(X+Y)—5(X—Y)=2(X+Y)除以2+(X—Y)除以3=6和4(X+Y)—5(X—Y)=2
我说老大,你说明白点儿,是
X+Y/2-Y/3=6
4(X+Y)-5(X-Y)=2
还是
(X+Y)/(2+X)-Y/3=6
4(X+Y)-5(X-Y)=2
又或者
(X+Y)/2+(X-Y)/3=6
4(X+Y)-5(X-Y)=2
请明示!

487X平方+1900X-2=0
自己解吧
好象是这样```N年没做过数学题了```
