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 ☛ Check: NCERT Solutions Class 9 Maths Chapter 4 Video Solution: If the point (3, 4) lies on the graph of the equation 3y = ax + 7, find the value of a.NCERT Solutions Class 9 Maths Chapter 4 Exercise 4.3 Question 3 Summary: If the point (3, 4) lies on the graph of the equation 3y = ax +7, then the value of a = 5/3. ☛ Related Questions: Math worksheets and |
