Question

check whether (2,-2) is the solution of 2x-y=6

Answer 1

check it by putting the values in the given linear expression.

2(2)-(-2)=6

4+2=6  yest its true there for (2,-2) is the solution for given expression.

Answer 2

Given:

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.
