Question

What is the value of k if (2, 3) is a solution of 2x + 3y = k

Answer 1

Given: (2, 3) is a solution of the equation 2x + 3y = k.

To find: The value of k.

Answer:

$2x + 3y = k\ is\ a\ linear\ equation\ in\ two\ variables.\\x = 2\\y = 3\\2 \times 2 + 3 \times 3 = k\\4 + 9 = k\\13 = k\\\\Therefore, k = 13$
