Let $\"x\"$ = Lani's age
\n" ); document.write( "So Regie's age= $\"x%2B5\"$
\n" ); document.write( "Going back 5 years ago,
\n" ); document.write( " $\"%28Lanis+%28age%29+-5years%29+%2B+%28Regies+%28age%29+-+5years%29+=+25+years\"$
\n" ); document.write( " $\"x-cross%285%29%2Bx%2Bcross%285%29-5=25\"$
\n" ); document.write( " $\"2x=25%2B5\"$ ; $\"2x=30\"$
\n" ); document.write( " $\"x=15\"$ --------> Lani's age
\n" ); document.write( " $\"x=15%2B5=20\"$ ----> Regie's age
\n" ); document.write( ".
\n" ); document.write( "It make sense, 5 years ago Lani's age, $\"15-5=10+years\"$ + Regie's age, $\"20-5=15\"$ --------> 10+15=25 years
