Hello?

yes, it is. The brother's age is b. Jonna's age is 4 more than b, or b+4 The sum of the ages is (b) + (b+4), which is 2b+4

OH NOW I SAW WHAT HAPPENED! sum of ages.. we have two people.. which is Jonna and her brother b is Jonna's brother b is also Jonna herself +4 for "4 years older than "and it's also related to Jonna Jonna is b+4 because b represents the age and +4 is how much older she is compared to b only which is her brother. b+b+4 and combining like terms is 2b+4. Sorry about earlier xD!
