Answer:
, 
Step-by-step explanation:
We have a system composed of two equations
The first is a quadratic equation and the second is a linear equation.


To solve the system, equate both equations and solve for x

To solve the quadratic equation we must factor it.
You should look for two numbers a and c that when multiplying them obtain as result 5 and when adding both numbers obtain as result -6.
This is:

The numbers searched are -5 and -1
So

Finally the solutions to the system of equations are:
,
