Question

. Find k if (2, k) lies on 2x + y = 7

Answer 1

Answer:

The answer is $k=3$

Step-by-step explanation:

Since $(2,k)$ lies on $2x+y=7$, so $x=2,y=k$ must satisfy it

            $\Rightarrow 2(2)+k=7\\\Rightarrow 4+k=7\\\Rightarrow k=7-4\\\Rightarrow k=3$

Answer 2

Answer:

Answer is 3

Step-by-step explanation:

2x+y=7

points are (2,k)

put x=2 and y=k in equation

2×2+k=7

4+k=7

k=7-4

k=3
