解x-(1/10)x=【240-x+(1/10)x】(3/5)解x-(1/10)x=【240-x+(1/10)x】(3/5)解x-(1/10)x=【240-x+(1/10)x】(3/5)原方程可化为：
解x-(1/10)x=【240-x+(1/10)x】(3/5)
解x-(1/10)x=【240-x+(1/10)x】(3/5)
解x-(1/10)x=【240-x+(1/10)x】(3/5)
原方程可化为：
(9/10)x=[240- (9/10)x]*(3/5)
(9/10)x= 240*(3/5) - (9/10)x*(3/5)
(9/10)x + (9/10)x*(3/5)= 240*(3/5)
(9/10)x*（1 + 3/5)= 240*(3/5)
(9/10)x*（8/5）= 240*(3/5)
(9/10)x*8=240*3
(9/10)x=30*3
(1/10)x=10
解得x=100
解x-(1/10)x=【240-x+(1/10)x】(3/5)
(9/10)x=144-(3/5)(9/10)x
(9/10)x+(3/5)(9/10)x=144
(8/5)(9/10)x=144
(36/25)x=144
x=144(25/36)
x=100
