How to find the point of interception for

For this case we have the following system of equations:

We multiply the second equation by -2:

Then we have the following equivalent system:

We add the equations:

Thus, the value of the variable y is 1.

We look for the value of the variable x:

Thus, the value of the variable x is 2.

Then the point of intersection of the equations is in

The point of intersection of the equations is in
