Question

3. Find the value of k, if x = 2, y = 1 is a solution of the equation 2x + 3y = k (b) 6 (c) 5 (d) 2 ​

Answer 1

Answer:

7

Step-by-step explanation:

According to the question:

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

Hence, k = 2x + 3y = (2*2) + (3*1) = 4 + 3 = 7

Answer 2
