 Hi, and welcome to the session. Let's discuss the following question. The question says, if the point 3, 4 lies on the graph of the equation 3y is equal to ax plus 7, find the value of a. Before solving this question, we should know that every point on the graph is a solution of linear equation. This is the key idea in this question. Start the solution. Since the point 3, 4 lies on the graph of equation 3y is equal to ax plus 7. Therefore, this implies that the point 3, 4 is a solution of the given equation. Point 3, 4 must satisfy this equation. So let's now substitute this point in this equation. Now here, x is equal to 3 and y is equal to 4. So by substituting x as 3 and y as 4, we get 3 into 4 is equal to a into 3 plus 7. And this implies 12 is equal to 3a plus 7. And this implies 12 minus 7 is equal to 3a. And this implies 5 is equal to 3a. And thus, a is equal to 5 by 3. Hence, the value of 5 by 3. This is our required answer. Bye and take care. Hope you have enjoyed the session.
