解方程:300x+150(50-x)+200(42-x)+150(x-2)=16000
解方程:300x+150(50-x)+200(42-x)+150(x-2)=16000
300x+150(50-x)+200(42-x)+150(x-2)=16000
300x+7500-150x+8400-200x+150x-300=16000
100x+15600=16000
100x=400
x=4
我刚才就给你改过来了
你却采纳了别人!
300x+150(50-x)+200(42-x)+150(x-2)=16000
解;300x+7500-150x+8400-200x+150x-300=16000
100x+15600=16000
...
