Answer:

Step-by-step explanation:
We can solve this system just by summing each side of the equation:
So, both left sides will be sum, and both right sides too.
The resulting expression will be:

Ordering and solving both sides:

Hence, the value to the system is 
It's important to combine both equation, because the exercise is asking for the solution of the system.
