You can put this solution on YOUR website!
Use y for Kim's age and x for Caitlin's.\r
\n" ); document.write( "\n" ); document.write( "x = 21
\n" ); document.write( "3y - 6 = x\r
\n" ); document.write( "\n" ); document.write( "Sub 21 for x\r
\n" ); document.write( "\n" ); document.write( "3y - 6 = 21\r
\n" ); document.write( "\n" ); document.write( "Add 6 to both sides.\r
\n" ); document.write( "\n" ); document.write( "3y = 27\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 3.\r
\n" ); document.write( "\n" ); document.write( "y = 9
\n" ); document.write( "
\n" );
