You can put this solution on YOUR website!
For this you need to collect like terms, any terms in the equation that look alike, you can add or subtract them.
\n" ); document.write( "-3r+5-3s-7+8s-2t-r
\n" ); document.write( "What I do to start is to put together like terms;
\n" ); document.write( "-3r-r+5-7-3s+8s-2t
\n" ); document.write( "Now I add or subtract the terms which are alike:
\n" ); document.write( "-4r -2 +5s -2t
\n" ); document.write( "Be very careful of the signs, remember the sign in front if the term goes with that term;
\n" ); document.write( "example;
\n" ); document.write( "when you move together the -3r with the -r, be sure the sign of the r moves with it.
\n" ); document.write( ":) \n" ); document.write( "
