For this case we have the following system of two equations with two unknowns:

$x + y = 10\\x-y = -2$

We want to know if the point
(x, y) = (6,4) is the solution of the system:

We replace:

6 + 4 = 10 , meets the first equation.

6-4 = 2, does not comply with the second equation.

Therefore, it is not system solution.

Answer:

The point is not system solution
