equations that I created. Want to see if they are correct.

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.Solve your system of equations by the addition/subtraction method. 

The solutions are 12 and 6

addition equation:

x-3=3

x-6+0=3+3

x+0=6

x+6

check:

x-0=6

6-0=6

6=6

subtraction method:

x + 6=12

x +6-6=12-6

x+0=6

x=6

check:

x + 6= 12

6+6=12

12=12

You need to find a system of 2 equations and 2 variables (x and y).
