Select any two integers between -12 and +12 which will become solutions to a system of two equations.
----
Example: Select x = -5 and y = +7
--------------------------------
Write two equations that have your two integers as solutions.
2x+3y = 11
-x+2y = 19
---------------------------

Show how you built the equations using your integers. Solve your system of equations by the addition/subtraction method.
----
Solve:
Multiply the 2nd equation by 2:
2x+3y = 11
-2x+4y = 38
-----
Add and solve for "y":
7y = 49
y = 7
-----
solve for "x":
2x+3y = 11
2x + 3*7 = 11
2x + 21 = 11
2x = -10
X = -5
