Answer:
Correct choice: B
Explanation:
System of non-linear equations
It's given the following system of equations:


We'll use the substitution method. Substituting y from the first equation into the second equation, we have:

Moving all terms to the left side:

Simplifying:

Factoring:

There are two solutions:
x=-4, x=2
The first solution gives a value for y:
y=-4+13=9
First solution: (-4,9)
The second solution gives a value for y:
y=2+13=15
Second solution: (2,15)
Correct choice: B
