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

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

Answers (1)

Answer:

a=\frac{5}{3}

Solution:

The given linear equation is 3y = ax + 7 and the point is (3, 4)

If the point (3, 4) lies on the graph of equation 3y = ax + 7 then it will surely satisfy the equation

Put value of x = 3 and y = 4 in equation 3y = ax + 7

3(4) = a(3) + 7

12 = 3a + 7

12 – 7 = 3a

5 = 3a

\frac{5}{3}=a
