Question

if point (-2,5) lies on graph of equation ax+3y=7 find value of a​

Answer 1

Answer:

a = 4

Step-by-step explanation:

The coordinates of the point are (-2, 5).

And it lies on the graph of equation :

ax + 3y = 7

So, put the values of x and y (-2, 5) in the given equation.

According To Question ―

ax + 3y = 7

a × (-2) + 3 × 5 = 7

-2a + 15 = 7

-2a = 7 - 15

-2a = -8

a = -8

-2

Therefore, a = 4.
