You can put this solution on YOUR website!
Reggie's age = \"x+5\"
\n" ); document.write( "why? because laarni's age = \"x\"
\n" ); document.write( "Five years ago:
\n" ); document.write( " $\"x%2B5-highlight%285%29%2Bx-highlight%285%29=25\"$ ----------------> working eqn
\n" ); document.write( "substract 5 yrs from their ages and sum up to 25.
\n" ); document.write( "Continuing:
\n" ); document.write( " $\"x%2Bcross%285%29-cross%285%29%2Bx-5=25\"$
\n" ); document.write( " $\"2x=25%2B5\"$
\n" ); document.write( " $\"cross%282%29x%2Fcross%282%29=cross%2830%2916%2Fcross%282%29\"$
\n" ); document.write( " $\"x=15\"$ -------------------------> Laarnis' age
\n" ); document.write( " $\"x%2B5=15%2B5=20\"$ ------------------> reggie's age
\n" ); document.write( "To check, 5 years ago: Go back working eqn
\n" ); document.write( " $\"20-highlight%285%29%2B15-highlight%285%29=25\"$
\n" ); document.write( " $\"15%2B10=25\"$
\n" ); document.write( " $\"25=25\"$
\n" ); document.write( "Thank you,
