Question

find the value of k if x = 2, y =1in the equated 2x +3y= k​

Answer 1

Given,

x=2, y=1

2x+3y=k

2×2+3×1=k

4+3=7

Therefore k= 7

Answer 2

Solution :

$\bf 2x + 3y = k$

Now, we are given x = 2 and y = 1

So, by putting values, we get :

$\bf : \implies 2 (2) + 3 (1) = k$

$\bf : \implies 2 \times 2 + 3 \times 1 = k$

$\bf : \implies 4 + 3 = k$

$\bf : \implies 7 = k$

$\bf : \implies k = 7$

$\Large \boxed {\bf k = 7 }$

Hence, value of k = 7.
