If the point (3, 4) lies on the graph of the equation 3y = ax + 7, find the value of a.

Given equation: 3y = ax + 7


⇒ ax = 3y – 7



Since, the point (3, 4) lies on the graph of the equation 3y = ax + 7 therefore, it should satisfy the equation 3y = ax + 7


So, x = 3 and y = 4


Putting these values we get,
