12) जर (3, 2) हा बिंदू 5x + ay = 19 या समीकरणाच्या आलेखावर असेल तर, ची किंमत काटा. If the point (3, 2) lies on the graph of the equation 5x + ay = 19, ther, find the value of a. a) 4 b) 2 c) 1 d) 3​

Answer 1

Step-by-step explanation:

Given: If the point (3, 2) lies on the graph of the equation 5x + ay = 19.

To find: Find the value of a.

a) 4

b) 2

c) 1

d) 3

Solution:

We know that if a point lies on equation it must satisfy the equation.

Step 1: Put x=3 and y=2 in the equation

$5(3) + a(2) = 19$

Step 2: Simplify and solve

$15 + 2a = 19 \\ \\ 2a = 19 - 15 \\ \\ 2a = 4 \\ \\ a = \frac{4}{2} \\ \\ a = 2$

Final answer:

Option (b) is correct.

Value of a=2, If the point (3, 2) lies on the graph of the equation 5x + ay = 19.

Hope it helps you.
