\"2x-3y=4\"
\n" ); document.write( "\"5x%2B2y=-9\"
\n" ); document.write( "since one y value is negative and other is possitive all we need to do is just get the number before y to be the same number so when adding together they cancel out. i just use the same numbers from other equation
\n" ); document.write( "\"2%282x-3y%29=2%284%29\" 2y from second equation tells me to multiply by 2
\n" ); document.write( "\"3%285x%2B2y%29=3%28-9%29\" 3y from first equation tells me to multiply by 3
\n" ); document.write( ".multiply
\n" ); document.write( "\"4x-6y=8\"
\n" ); document.write( "\"15x%2B6y=-27\"
\n" ); document.write( ".add them together
\n" ); document.write( "\"19x=-19\"
\n" ); document.write( "\"x=-1\"
\n" ); document.write( ".
\n" ); document.write( "\"2x-3y=4\"
\n" ); document.write( "\"2%28-1%29-3y=4\"
\n" ); document.write( "\"-2-3y=4\"
\n" ); document.write( "\"-3y=6\"
\n" ); document.write( "\"y=-2\"
\n" ); document.write( ".
\n" ); document.write( "(\"-1\",\"-2\")
\n" ); document.write( "
\n" );
