\n" );
document.write( "I have to choose two integers between -12 and +12. then write two equations that have my two integers as solutions and show how i built the equations using my two integers. for example: x=12 and y=5. then solve my system of equations by the addition/subtraction method. I have been working on this for 2 hours and just cannot get it right in my head. \n" );
