Question

find the value of k, if x = 2,y= 1 is a solution of the equation 2x + 3y = K.​

Answer 1

Answer:

7

Step-by-step explanation:

2×2+3×1=7 because X=2 and y= 1

Answer 2

Solution:

The given equation is

2x+3y = k

According to the question, x = 2 and y = 1.

Now, Substituting the values of x and y in the equation2x+3y = k,

We get,

(2×2)+(3×1) = k

⟹ 4+3 = k

⟹ 7 = k

k = 7

The value of k, if x = 2, y = 1 is a solution of the equation 2x+3y = k, is 7.
