You can put this solution on YOUR website!
I think you are looking for the \"reasons\" after each \"statement\"\r
\n" ); document.write( "\n" ); document.write( "1. 3x - 7 = -4 REASON \"given\"
\n" ); document.write( "2. 3x - 7 + 7 = -4 + 7 REASON \"addition property of equality\"
\n" ); document.write( "3. 3x + 0 = -4 + 7 REASON \"inverse property of addition\"
\n" ); document.write( "4. 3x + 0 = 3 REASON \"distributive property\" - I know weird but true.
\n" ); document.write( "5. 3x = 3 REASON \"identity property of addition\"
\n" ); document.write( "6. (1/3) 3x = 3 (1/3) REASON \"multiplicative inverse property\" - you may have division in book.
\n" ); document.write( "7. (1/3) 3x = 1 REASON \"any number, except 0, times its reciprocal is 1\"
\n" ); document.write( "8. 1x = 1 REASON \"any number, except 0, times its reciprocal is 1\"
\n" ); document.write( "9. x = 1 REASON \"identity property of addition\" \n" ); document.write( "
\n" );
