Question

find the value of a if (-1 , 1) is a solution of the equation 3x- ay = 5 . ​

Answer 1

Answer:

a = -8

Step-by-step explanation:

x = -1 , y = 1

Substitute in the given eqn

3×-1 - a×1 = 5

-3 - a = 5

a = -(5+3)

a = -8

Answer 2

Answer:

=> The value of a is -8.

Step-by-step explanation:

Given that:-

$3x-ay=5$

If, ( -1, 1 )

To find - The value of a,

Let, ( x, y ) = ( -1, 1 )

Now, plug the values of x and y as -1 and 1 in the equation:

As we have,

$=> 3x-ay=5$

$=> 3(-1)-a(1)=5$

$=> (-3)-a=5$

$=> a = 5+3$

$=> a = 8$

Hence, the value of a is 8.
