Alex is 5 years older than Adrianna. In 6 years the sum of their ages will be 83. How old is Alex now?

Answer 1

If the sum of their ages will be 83 in 6 years, the sum now is 71. That’s because you need to subtract 6 for each of them, and 83-12=71. So if Alex is 5 years older, we can make him x+5, and Adrianna x. So then x + x + 5 = 71, and 2x + 5 = 71, and 2x = 66. Therefore, x = 33, so that Alex at x + 5 = 38.
