8x-9y=17
\n" ); document.write( "40x-45y=85 multiplied by 5
\n" ); document.write( ".
\n" ); document.write( "7x+5y=2 To eliminate y you must multiply by 9 to make the two y's add to zero.
\n" ); document.write( "63+45y=18
\n" ); document.write( ".
\n" ); document.write( "40x-45y=85
\n" ); document.write( "63x+45y=18
\n" ); document.write( "-----------add
\n" ); document.write( "103x = 103 making y disapear, leaving only x.
\n" ); document.write( "x=1
