First off, you have to convert \"Twenty more than twice a number is 52\" into an algebraic equation. To do this, simply break the question apart:
\n" ); document.write( "\"Twenty more than\" means \"20+\", because \"more than\" generally is telling you to add.
\n" ); document.write( "\"Twice a number\" means \"2*n.\" The reasoning behind this is that \"a number\" typically means a variable, and we'll use n in this case (Though it doesn't really matter which variable you pick.) And twice obviously means \"2 times.\"
\n" ); document.write( "\"is 52\" translates neatly into \"=52,\" because \"is\" means the same as \"equals\"
\n" ); document.write( "Thus, we arrive at the equation \"20+2*n=52\"
\n" ); document.write( "Since we have one equation and one variable, it should be pretty easy to solve:
\n" ); document.write( "20+2*n=52
\n" ); document.write( "Subtract 20 from both sides, so we can have the variable alone.
\n" ); document.write( "20+2*n-20=52-20
\n" ); document.write( "2*n=32
\n" ); document.write( "Now, we will divide both sides by two to find n's solution.
\n" ); document.write( " $\"%282%2An%29%2F%282%29=%2832%29%2F%282%29\"$
\n" ); document.write( "n=16 \n" ); document.write( "

\n" );
