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

Solution:

Given: Linear equation 3y = ax + 7.

We can find the value of 'a' by substituting the values of x and y in the given equation

By substituting the value of x = 3 and y = 4 in the the equation 3y = ax + 7, we get

3(4) = a(3) + 7

12 = 3a + 7

3a = 5

a = 5/3

Hence, the value a = 5/3
