5x-（-x）=106x=10x=5/3
则1/X-3X/4=4方程两边同乘4X得4-3X^2-16X=0解得X=(-16+4倍根号下13)/3或(-16-4倍根号下13)/3因为当X=(-16+4倍根号下13)/3或(-16-4倍根号下13)/3时4X不=0所以原方程的解为(-16+4倍根号下13)/3或(-16-4倍根号下13)/3
第二题有些复杂 看不懂
没法写分号所以看着乱
我整理一下
设这个数为X则1/X-3X/4=4
我知道了 谢谢
那这几题怎么做a
哦，等下，我用文件写一下，发过去
因为（a+b）×2=20，所以a+b=20÷2=10（厘米），ab=24，又因为4×6=24，并且4+6=10，所以长方形的长是6厘米，宽是4厘米；答：长方形的长是6厘米，宽是4厘米．故答案为：6厘米；4厘米．
但要得是方程喔
解题我懂 主要我不会写出来
设钢丝Xx-4/5x=31/5X=3X=3除于1/5
写不出来了
设全校有X人 52%X-(X-52%X)=800.52X-0.48X=800.04X=80X=80/0.04X=2000 全校2000人
这样能看懂吗？
我没法写除号，只能这样写了
解:设甲种x支,乙种20-x支 0.3x+0.6(20-x)=9 0.3x+12-0.6x=9 0.3x=3 x=10 20-x=10 答:甲乙两种各买了10支
第三题你会了吗？
不然我在写一遍
干嘛呢，一道也不会
我数学是渣渣
我的QQ给你，不会问我吧
我懂题目说什么 就是不会写出来
学好点，认真学才行呀
多简单的题呀
我一看就知道
只是写出来太麻烦
得现在文件上搭个草，复制过来
祝你学习开心哟
我想问，你英语会吗
以后不会可以找我^_^
英语问什么？
那个，我发给你吧
看不清楚了
我通常吃两碗米饭和蔬菜I usually eat two bowls of rice and vegetables
是这个吗？
打出来好费劲
里面还有其他东西吗？ There are also other things?
我通常吃两碗米饭和一些蔬菜
I usually eat two bowls of rice and some vegetables
