Question

If (2,2) lies on $4x+5y=k$, the value of $k$ is

___

Answer 1

If the point (2,2) lies on the given linear equation, then it must satisfy the equation.

Putting the value of x and y in the equation we get:

$\Rightarrow 4\left(2\right)+5\left(2\right)=k$

$\Rightarrow k=18$

Thus, the value of k is 18.
