Answer:
Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82.
Step-by-step explanation:
The sum of a number and 31 would be 'n + 31'. The sum equaling 113 would be '= 113'.
You would get 'n' by subtracting 31 for each side.
![n+31 = 113\\n+31-31=113-31 \leftarrow \text{Subtraction Property of Equality} \\\boxed{n=82}](https://tex.z-dn.net/?f=n%2B31%20%3D%20113%5C%5Cn%2B31-31%3D113-31%20%5Cleftarrow%20%5Ctext%7BSubtraction%20Property%20of%20Equality%7D%20%5C%5C%5Cboxed%7Bn%3D82%7D)
The statement: "Write the equation as n + 31 = 113 and subtract 31 from both sides. The answer is 82." should be the correct answer.

Step-by-step explanation:
The solutions to the systems of equations are at the points of intersection of the 2 graphed functions.
1
There are 2 points of intersection , so 2 solutions at
(0, - 3 ) and (4, 5 )
2
There is 1 point of intersection, so 1 solution at
(- 2, 5 )
3
There are no points of intersection , so no solution
