document.write( "Okay, lets get started. First, we need to set up an equation. Let's call his sister's weight \"x\" for now.<BR>\n" );
document.write( "74+x=3x+6<BR>\n" );
document.write( "Now, let us subtract 6 from both sides.<BR>\n" );
document.write( "74-6+x=3x+6-6 which equals<BR>\n" );
document.write( "68+x=3x<BR>\n" );
document.write( "Now, lets subtract an x from both sides<BR>\n" );
document.write( "68+x-x=3x-x which equals<BR>\n" );
document.write( "68=2x<BR>\n" );
document.write( "Finally, we should divide both sides by 2 to get rid of the 2 in front of the x.<BR>\n" );
document.write( "68/2=2x/2<BR>\n" );
document.write( "x=34, so his sister's weight is 34 pounds.<BR>\n" );
