Brittney is 5 years older than her brother Brandon. Three years from now, the sum of their ages will be 23. How old is Brandon now?

Answer 1

6 + 11 =17 now

3 years from now

9 + 14 = 23

Answer 2

proper steps:

present age of Brandon ---- x
present age of Brittney ----- x+5

Three years from now:
Brandon------> x+3
Brittney -------> x+5+3 = x+8

x+3 + x+8 = 23
2x = 12
x = 6

Brandon is now 6, and Brittney is 11
