You can put this solution on YOUR website!
-7x + 4x = 9
\n" ); document.write( " add like terms\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "rules of addition
\n" ); document.write( "opposite sign: subtract
\n" ); document.write( "same sign: add
\n" ); document.write( "take sign of larger #\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "7x-4x=3x and since the -7 is bigger, it is -3x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-3x=9
\n" ); document.write( "divide both sides by -3
\n" ); document.write( "x=-3
\n" ); document.write( "
