\n" ); document.write( " How long will it be before you have as much money as your sister.
\n" ); document.write( " This is what I have so far:
\n" ); document.write( "The sister is subtracting 7$ each week, from her savings of $145
\n" ); document.write( "80 + 6x = 145 - 7x
\n" ); document.write( "6x + 7x = 145 - 80
\n" ); document.write( "13x = 65
\n" ); document.write( "x = 65/13
\n" ); document.write( "x = 5 weeks
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "confirm this by finding how much each will have
\n" ); document.write( "80 + 6(5) = 110
\n" ); document.write( "145 - 7(5) = 110 \n" ); document.write( "
\n" );
