Question

If (a, -2) lies on the graph of 3x-y = 10, then the value of a is -

a. 4 b. 8/3 c. 0 d. 1​

Answer 1

Answer:

Step-by-step explanation:

From this we know that x = a and Y = -2

3x-y =10

3a -2 = 10

To find = a

3a = 10 + 2

3a = 12

a = 12/3

Ans ⇒ a = 4

Answer 2

Answer:

If (a, -2) lies on the graph of 3x-y = 10, then the value of a is -

a. 4 b. 8/3 c. 0 d. 1

→a. 4
