\n" ); document.write( "My answer ended up being (-4,5), but my friend says the answer is (-4,3). We are both terribly confused ! When we check the equation both answers are correct.\r

You can put this solution on YOUR website!
The -3 equation transforms easily to x+y=-1, and the \"17\" equation becomes -5x-y=17.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Summary of System:
\n" ); document.write( "-5x-y=17
\n" ); document.write( "x+y=-1\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Add both equations: -4x+0=16; therefore, x=-4.
\n" ); document.write( "Substitute the value into either equation.
\n" ); document.write( "-4+y=-1
\n" ); document.write( "y=+4-1
\n" ); document.write( "y=+3
\n" ); document.write( "Answer: point (-4,3)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "When you check, you found both answers as correct?
\n" ); document.write( "Let's try the other point you or the friend found, (-4,5):
\n" ); document.write( "-5*(-4)-(5)=17?
\n" ); document.write( "20-5=17?
\n" ); document.write( "15=17? NO. \n" ); document.write( "
\n" );
