No. See below, the second equation is not solve therefore this point is not a solution for this set of equations.

#### Explanation:

To determine if this point is a solution to the system of equations we need to substitute the point into each equation and see if it solves the equation.

We will substitute

Then

And

Because the second equation is not solve this point is not a solution for this set of equations.
