You can put this solution on YOUR website!
Since the absolute value of a number is the POSTIVE DISTANCE FROM ZERO, you can really have two answers |3| = 3 and |-3|=3
\n" ); document.write( "
\n" );
document.write( "Therefor the expression inside the absolute value bars can equal either 3 or -3, so you need to set up two separate expresstions representing that fact.
\n" );
document.write( "
\n" );
document.write( " Expression 1
\n" );
document.write( "
\n" );
document.write( "Add 13 to both sides
\n" );
document.write( "

document.write( "Divide by 6

document.write( "\n" );
document.write( "So either answer will work, if you plug in the Expression 1, you will get
\n" );
document.write( "|3| which is 3, if you plug in Expression 2, you will get |-3| which is ALSO 3
