Question

Determine whether (6,4) is a solution to the following system of linear equations: x + y=10.....x-y=-2*

Answer 1

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
