\n" ); document.write( "write an equation for each statement:
\n" ); document.write( "\" Rekha little sister is now 5 years old \"
\n" ); document.write( "s = 5
\n" ); document.write( "\"if her age is 2 years more than one forth of rekha age\"

\n" ); document.write( "replace s with 5 (from the first statement)
\n" ); document.write( "5 = \"1%2F4\"r + 2
\n" ); document.write( "get rid of the fraction, multiply both sides by 4
\n" ); document.write( "4(5) = 1r + 4(2)
\n" ); document.write( "20 = r + 8
\n" ); document.write( "subtract 8 from both sides
\n" ); document.write( "20 - 8 = r
