Question

Find the value of k, if (x = 2) and (y = 1) is a solution f the equation 2x + 3y - k.​

Answer 1

Step-by-step explanation:

2x + 3y = k

2×2 + 3×1 = k

4 + 3 = 7

Answer 》 k = 7

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
