We're going to apply the \"elimination\" method:
\n" ); document.write( "y=x+8
\n" ); document.write( "-x+3y=10
\n" ); document.write( ".
\n" ); document.write( "Move all the x's and y's to the left:
\n" ); document.write( "-x+ y= 8
\n" ); document.write( "-x+3y=10
\n" ); document.write( ".
\n" ); document.write( "Multiply both sides of the TOP equation by -1. Then combine BOTH equations together to eliminate the x term:
\n" ); document.write( " x- y=-8
\n" ); document.write( "-x+3y=10
\n" ); document.write( "-----------
\n" ); document.write( " 2y=2
\n" ); document.write( " y = 1
\n" ); document.write( ".
\n" ); document.write( "Now, we substitute y=1 into:
\n" ); document.write( "y=x+8
\n" ); document.write( "1=x+8
\n" ); document.write( "-7=x
\n" ); document.write( ".
\n" ); document.write( "solution: (x,y) = (-7,1)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
