 Hi, and welcome to the session. Let's discuss the following question. The question says, find the value of k if x equals to 2, y equals to 1 is a solution of the equation 2x plus 3y equals to k. Now, start the solution. Since x equals to 2 and y equals to 1 is a solution for the equation 2x plus 3y equals to k. Therefore, x is equal to 2, y equals to 1 must satisfy the equation plus 3y equals to k. Right, that means if I substitute the value of x and y in this equation, then it is equal to r and x. So let's now substitute the value of x and y x plus 3y equals to k. Now, x is equal to 2 and y is equal to 1. So we have 2 into 2 plus 3 into 1 equals to k. And this implies that 4 plus 3 is equal to k. Thus, k is equal to 7. Hence, the required value of k is 7. This is our required answer. Bye, and take care. Hope you have enjoyed the session.
