6000/x=10800/2x+20x=?6000/x=10800/2x+20x=?6000/x=10800/2x+20x=?约分10/x=9/(x+10)两边乘x(x+10)10x+100=9xx=

6000/x=10800/2x+20 x=?
6000/x=10800/2x+20 x=?

6000/x=10800/2x+20 x=?
约分
10/x=9/(x+10)
两边乘x(x+10)
10x+100=9x
x=-100

6000/x=10800/(2x)+20我猜你原本是要解这个
→6000/x=5400/x+20
→600/x=20
→x=30
而6000/x=10800/2x+20
→6000/x=5400x+20
→300/x=270x+1
→300=270x²+x
→x=-1/540+√32401/540或x=-1/540-√32401/540
