Question

If $x=3$ and $y=-2$ satisfy$2x–3y=k$, then find the value of $‘k’$.

Answer 1

Finding the value of $k$ :

The given equation is $2x-3y=k$.

Putting the values of $x=3$ and $y=-2$ we get,

$2\times 3-3\times \left(-2\right)=k$

$\Rightarrow 6-\left(-6\right)=k$

$\Rightarrow 6+6=k$

$\Rightarrow k=12$

Hence, the value of $k$ is $12$.
