Question

check weather (1,-2) is the solution for the equation 2x-y=6​

Answer 1

Answer:

it is not the solution for the equation 2x-y=6​

Step-by-step explanation:

2x-y =6

therefore

=2*1-(-2)

=4

so it is not a solution of

2x-y=6​

Answer 2

Step-by-step explanation:

2x - y = 6

and,

(x, y) = (2, -2)

To Find:

The given points are the solution of the given equation = ?

Solution:

On the putting the points in the given equation, we can check whether it is the solution of 2x - y = 6 or not.

So,

⇒  2x-y=6

⇒  2 (2) - (-2)=6

⇒  4+2=6

⇒  6=6

∴ LHS = RHS

So that it is the solution
