Question 445312: Select any two integers between -12 and +12 which will become solutions to a system of two equations.
Write two equations that have your two integers as solutions. Show how you built the equations using your integers. Your solution and equations should not be the same as those of other students or the textbook. There are infinite possibilities.
Solve your system of equations by the addition/subtraction method. Make sure you show the necessary 5 steps.
I have never taken a math class higher than Pre-algebra, and that was 35 years ago. I am taking a course online and am having difficulty intrpreting the material. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Select any two integers between -12 and +12 which will become solutions to a system of two equations.

Let x = 3
Let y = -2
-----
Form 2 equations in x and y:
----------------------------------
2x + y = 4
-x +2y = -7
-------------------
Solve the system:
Multiply the bottom equation by 2:
2x + y = 4
-2x +4y = -14
----------------------
Add the 2 equations and solve for "y":
5y = -10
y = -2
---
solve for "x":
2x+y = 4
2x - 2 = 4
2x = 6
x = 3
------------------
Solution: x= 3 ; y = -2
