Hi, for this one we know we are going to have x to represent Brittany's brothe's age and since Brittany is five years older, that means she is plus five years, or we are going to add five years to x to find her age. So our equation for this situation is x+5=21. Hope this helps and let me know if you have any more questions. :) \n" ); document.write( "
