Answer:
value of a = 5/3
Step-by-step explanation:
(3,4) lies on the graph of the equation 3y = ax+7
putting value of x and y
3y = ax+7
3*4 = a*3 + 7
12 = 3a+7
3a = 12-7
3a = 5
a= 5/3

Solution :
The given equation is → 3y = ax+7
According to the question, x = 3, y = 4
Now,Substituting the values of x and y in the equation 3y = ax+7,we get,
(3×4) = (a×3)
⇒ 12=3a + 7
⇒ 3a + 7 = 12
⇒ 3a = 12 - 7
⇒ 3a = 5
⇒ a =
The value of a, if the point (3,4) lies on the graph of the equation 3y=ax+7 is 5/3.
