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

Text Solution

Verified by Experts

The correct Answer is:
A
Since, (2,0) is a solution of the given linear equation 2x+3y=k, then put x=2 and y=0 in the equation.
`implies " " 2(2)+3(0)=k impliesk=4`
Hence, the value of k is 4.
