Ja = Jack's present age
\n" ); document.write( "Ji = Jill's present age
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "Jack is twice as old as Jill.
\n" ); document.write( "Ja = 2Ji
\n" ); document.write( ":
\n" ); document.write( "In 2 years, Jack will be 4 times as old as Jill was 9 years ago.
\n" ); document.write( "Ja + 2 = 4(Ji - 9)
\n" ); document.write( ":
\n" ); document.write( "Ja + 2 = 4Ji - 36
\n" ); document.write( ":
\n" ); document.write( "Ja = 4Ji - 36 - 2
\n" ); document.write( ":
\n" ); document.write( "Ja = 4Ji - 38
\n" ); document.write( ":
\n" ); document.write( "Replace Ja with 2Ji, find Ji
\n" ); document.write( "2Ji = 4Ji - 38
\n" ); document.write( ":
\n" ); document.write( "38 = 4Ji - 2Ji
\n" ); document.write( ":
\n" ); document.write( "38 = 2Ji
\n" ); document.write( "Ji = \"38%2F2\"
\n" ); document.write( "Ji = 19 yrs is Jill's present age
\n" ); document.write( "then
\n" ); document.write( "2(19) = 38 yrs is Jack's present age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check our solution in the statement
