Question
If the point (3, 4) lies on the graph of 3y = ax + 7, then find the value of a.
Solution
Consider the linear equation:
3y = ax + 7
The point (3, 4) lies on the graph of 3y = ax + 7.
So, this point will be satisfy the given equation, get:
3y = ax + 7
12 = 3 × a + 7
12 – 7 = 3a
3a = 5
`a = 5/3`
Hence, the value of a is `5/3`.
