Question

If $(2,0)$ is a solution of the linear equation $2x+3y=k$, then the value of $K$ is

• A. $4$
• B. $6$
• C. $5$
• D. $2$

Answer 1

The correct option is A

$4$

Find the required value:

Given : $(x,y)=(2,0)$ , $2x+3y=k$

Putting values in the given equation, we get

$$\begin{gathered} 2\left(2\right)+3\left(0\right)=k \\ \Rightarrow 4+0=k \\ \boxed{\Rightarrow k=4} \end{gathered}$$

Therefore, the value of $k$ is $4$.

Hence, option $A$ is the correct answer.
