Linear Equation in one variable means
- Only one variable
- An = sign
- Highest power 1
Let’s take some examples
x + 1 = 0
Here,
- There is only 1 variable − x
- There is an equal sign
- Highest power of x is 1 (x ^{ 1 } = x)
∴ It is linear equation in one variable
2x + 3 = 0
Here,
- There is only 1 variable - x
- There is an equal sign
- Highest power of x is 1 (x ^{ 1 } = x)
∴ It is linear equation in one variable
4x + 5 = 108
Here,
- There is only 1 variable - x
- There is an equal sign
- Highest power of x is 1 (x ^{ 1 } = x)
∴ It is linear equation in one variable
3x
There is no equal sign
∴ It is not a linear equation in one variable
4x ^{ 2 } + 1 = 0
Highest power of x = 2
∴ It is not a linear equation in one variable
3x + 2y = 3
Here, we have two variables x & y
∴ It is not a linear equation in one variable
