我该如何解决这个问题？ X + 4y = 6 y = -x + 3 [英] How do I solve this problem? X+4y=6 y=-x+3

问题描述

在这个问题中你将解决具有替换的方程组。



我尝试过的方法：



没什么。我非常坚持这个问题。

In this problem you would be solving systems of equations with substitution.

What I have tried:

Nothing. I'm pretty stuck on this problem.

推荐答案

两件事：

1）这是正常的，无聊的数学：一个非常简单的替代问题。你的上一课将教你如何解决它们。这是一个软件开发网站，而不是数学很有趣的网站，所以你在错误的地方发帖。



2）我们不做你的作业：这是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



亲自尝试，或学习魔术词： 你想要炸薯条吗？

Two things:
1) That is normal, boring maths: a very simple substitution problem. Your last lecture will have taught you how to solve them. This is a software development site, not a "maths is fun" site, so you are posting in the wrong place.

2) We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, or learn the Magic Words: "Do you want fries with that?"
