Jeanna has two brothers, ages 3 and 5

She is 4 years older than the sum of their ages

Sum is addition

( 3 + 5 ) + 4

The + 4 is because to find out how old Jeanna is,

You need to add her age to her brothers' ages

So 8 + 4 = 12

Jeanna is 12 years old

Hope this helps

her brothers's ages are 3 year old and 5 year old.

Jeanna is four years older than the sum (5 + 3) of her brothers.

Let jeanna = j, set the equation:

j = 5 + 3 + 4

Simplify

j = 8 + 4

j = 12

12 years old is your answer
