Question

Linear equation in one variable has?

• A. One Solution
• B. Two Solution

Answer 1

The correct option is A

One Solution

Define the linear equation in one variable

1. The standard form of a linear equation in one variable is $ax+b=0$.
2. Here, $a$ and $b$ are two integers and $a\ne 0$, and $x$ is a variable.
3. The highest power of the variable is $1$.
4. A linear equation in one variable has only one solution.

For example,

Let the linear equation in one variable is $23m+9=32$.

On simplifying the above, we get,

$23m=32-9$

$\Rightarrow$ $23m=23$

$\Rightarrow$ $m=1$

From the above example, it is clear that a linear equation in one variable has only one solution.

Hence, option (A) is the correct option.
