\n" );
document.write( "\n" );
document.write( "i subtracted 2x from the first equation to get y-2x=9 and subtracted 7x from the second to get y-7x=8\r
\n" );
document.write( "\n" );
document.write( "i then used substitution method to get 7(2x-y)-y=8 to get 14x-7y-y=8, but i dont know if that is correct to get to the final steps.? \n" );
