You can put this solution on YOUR website!

\n" ); document.write( "You should be making two equations with two unknowns.
\n" ); document.write( "You substituted 3w for w instead of 3w for e
\n" ); document.write( "Don't use x for multiplication sign
\n" ); document.write( "Use the asterisk above the number 8
\n" ); document.write( "Also we usually put numbers before letters
\n" ); document.write( "3w not w3
\n" ); document.write( "w3 can be confused for w^3
\n" ); document.write( "Mathematics is a language and has rules just like English and Spanish
\n" ); document.write( "and it has its own vocabulary and word order.\r
\n" ); document.write( "\n" ); document.write( "e=3w
\n" ); document.write( "(e+4)=2(w+4)
\n" ); document.write( "substitute 3w for e
\n" ); document.write( "3w+4=2w+8
\n" ); document.write( "subtract 2w from both sides
\n" ); document.write( "subtract 4 from both sides\r
\n" ); document.write( "\n" ); document.write( "w=4
\n" ); document.write( "e=3*w=12
\n" ); document.write( "check\r
\n" ); document.write( "\n" ); document.write( "12+4=2(4+4)
\n" ); document.write( "16=2*8
\n" ); document.write( "16=16
\n" ); document.write( " \n" ); document.write( "
\n" );
