Question

If (2, 0) is a solution of the linear equation 2x + 3y = k then the value of k is
(a) 6
(b) 5
(c) 2
(d) 4

Answer 1

Since, (2, 0) is a solution of the linear equation 2x + 3y = k.

Substituting the values x = 2 and y = 0 in the equation 2x + 3y = k, we get

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

Hence, the correct option is (d).
