在解决数学问题时,您可能见过各种类型的方程。很少有方程只能包含数字,有些方程仅包含变量,而有些方程则同时包含数字和变量。
线性和非线性方程通常由数字和变量组成。
在开始介绍线性方程和非线性方程的区别之前,让我们先了解一下线性方程和非线性方程的定义。
线性方程:线性方程是形成一条直线的方程。线性意味着与线相关的事物。所有线性方程都用于构造一条直线。线性方程是主要要求的条件。这些条件的特点是排列框架中的线条。直线方程称为线性方程。直线条件的整体描绘是y=mx+b,其中m是直线的斜度,b是y-catch。
非线性方程:非线性方程不形成直线。它看起来像图中的一条曲线,并且具有可变的斜率值。非线性方程通常由 ax 2 +by 2 = c 给出
其中 x 和 y 是变量
a、b 和 c 是常数值。
这里给出了线性方程和非线性方程的主要区别,让学生以更自然的方式理解它。差异以表格形式提供,并附有示例。
要找出两个方程(即线性方程和非线性方程)之间的区别,应该知道它们的定义。因此,让我们定义并查看它们之间的区别。
S No. | Linear Equations | Non-Linear Equations |
1. | It forms a straight line or represents the equation for the straight line | It does not form a straight line but forms a curve. |
2. | It has only one degree. Or we can also define it as an equation having the maximum degree 1. | A nonlinear equation has the degree as 2 or more than 2, but not less than 2. |
3. | All these equations form a straight line in XY plane. These lines can be extended to any direction but in a straight form. | It forms a curve and if we increase the value of the degree, the curvature of the graph increases. |
4. |
The general representation of linear equation is; y = mx +c Where x and y are the variables, m is the slope of the line and c is a constant value. |
The general representation of nonlinear equations is; ax2 + by2 = c Where x and y are the variables and a, b and c are the constant values |
5. | Linear Equations are much simpler to solve. | Non-linear Equations are tricky in nature. |
6. | Linear Equations are time saving. | Non-linear equations are time-consuming. |

线性和非线性方程的示例问题
问题 1:求解线性方程 3x+18 = 2x + 21。
解决方案:
Given, 3x+18 = 2x + 21
⇒ 3x – 2x = 21 – 18
⇒ x = 3
问题 2:求解 x = 12(x +2)
解决方案:
x = 12(x + 2)
x = 12x + 24
Subtract 24 from each side
x – 24 = 12x + 24 – 24
x – 24 = 12x
Simplify
11x = -24
Isolate x, by dividing each side by 11
11x / 11 = -24/11
x = -24/11
问题 3:求解非线性方程 x+4y = 1 和 x = y。
解决方案:
Given, x+4y = 1
x = y
By putting the value of x in the first equation we get,
⇒ y + 4y = 1
⇒ 4y = 1
⇒ y = 1/4
∴ x = y = 1/4
问题 4:示例:求解非线性方程 x+2y = 1 和 x = 2
解决方案:
Given, x+2y = 1
x = 2
By putting the value of x in the first equation we get,
⇒ 2+ 2y = 1
⇒ 2y = -1
⇒ y = -1/2
∴ y=-1/2
