Question

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

Answer 1

Hope that helps you!

All you have to do is substitute and multiply.

Chill, you got it!

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
