方程是数学中常见的问题解决工具,通过将未知数与已知数进行运算和比较,来寻找未知数的值。在本文中,我们将探讨方程2x-4=2-7x的解。
首先,我们可以通过整理方程,将x的项放在一边,常数项放在另一边。进行这样的整理,可以使我们更清晰地看到方程中的未知数。将方程重写为2x+7x=2+4。
接下来,我们可以合并同类项,将所有的x项相加,并将所有的常数相加。这将得到一个新的方程,9x=6。
为了求解x的值,我们需要将方程两边同时除以9。这样,我们就可以得到x=6/9。
简化这个分数,我们可以得到x=2/3。所以,方程2x-4=2-7x的解是x=2/3。
Equation is a common tool in mathematics to solve problems. By performing operations and comparisons between unknowns and knowns, we can find the value of an unknown. In this article, we will explore the solution to the equation 2x-4=2-7x.
Firstly, we can rearrange the equation by putting the terms with x on one side and the constant terms on the other side. This rearrangement allows us to see the unknown more clearly. Rewrite the equation as 2x+7x=2+4.
Next, we can combine like terms by adding all the x terms together and adding all the constant terms together. This will give us a new equation, 9x=6.
To solve for x, we need to divide both sides of the equation by 9. This will give us x=6/9.
Simplifying this fraction, we get x=2/3. Therefore, the solution to the equation 2x-4=2-7x is x=2/3.
