一元一次方程解决配套问题应用题

一元一次方程是元次应用小学数学中的基础内容，也是解决中学数学中不可避免的重点。在实际生活和工作中，配套我们可以利用一元一次方程来解决配套问题，问题例如购物打折、元次应用计算收入等等。解决

以购物打折为例，配套假设小明在商场购买一件原价为100元的问题衣服，商家打折5折，元次应用即打5折后的解决价格为x元。那么，配套我们可以通过一元一次方程来求解这个问题。问题

首先，元次应用我们可以列出一个方程表示打折后的解决价格：

x = 100 × 0.5

其中，100表示原价，配套0.5表示打5折，x表示打折后的价格。我们可以将式子简化为：

x = 50

这个式子的意思是，小明购买这件衣服打折后的价格是50元。通过一元一次方程，我们可以轻松地算出小明购物的实际价格。

再举一个例子，假设小红每小时可以做10道数学题，她做了t小时，共做了30道数学题。那么，我们可以通过一元一次方程来计算小红一小时做题的效率。

首先，我们可以列出一个方程表示小红做题的效率：

10t = 30

其中，10t表示小红t小时内做的题目数量，30表示总共做的题目数量。我们可以将式子简化为：

t = 3

这个式子的意思是，小红每小时可以做3道数学题。通过一元一次方程，我们可以计算出小红的实际效率。

可以看出，一元一次方程可以帮助我们解决很多实际问题，尤其是在计算配套问题方面，使用一元一次方程更为方便快捷。掌握一元一次方程的方法和技巧，可以让我们更好地应对生活和工作中的数学问题。
