\n" ); document.write( "let Cesar ‘s age be $\"C\"$ and Haley's age $\"H\"$ \r
\n" ); document.write( "\n" ); document.write( "if Cesar is $\"18+\"$ years younger than Haley, we have\r
\n" ); document.write( "\n" ); document.write( " $\"C=H-18\"$ ....eq.1\r
\n" ); document.write( "\n" ); document.write( " if $\"7\"$ years ago, Haley's age was $\"2\"$ times Cesar's age, we have\r
\n" ); document.write( "\n" ); document.write( " $\"H-7=2%28C-7%29\"$ ....eq.2......substitute $\"C\"$
\n" ); document.write( " $\"H-7=2%28H-18-7%29\"$
\n" ); document.write( " $\"H-7=2%28H-25%29\"$
\n" ); document.write( " $\"H-7=2H-50\"$
\n" ); document.write( " $\"50-7=2H-H\"$
\n" ); document.write( " $\"43=H\"$ \r
\n" ); document.write( "\n" ); document.write( "go to
\n" ); document.write( " $\"C=H-18\"$ ....eq.1....substitute $\"H\"$
