Question

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

Answer 1

answer:

K=7

Step-by-step explanation:

given= 2x+3y=K ( x=2,y=1) to find K=?

now,put the value of x and y in the equation

given.

(2×2) + (3×1)= K

4 + 3 = K

7= K ans.

Answer 2

Given equation is 2x+3y=k

According to question x=2,y=1

Now substituting the values of x and y in the equation 2x+3y=k,we get,

(2×2)+(3×1)=k

⇒ 4+3=k

⇒ 7=k

So, k = 7

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