<human>:  Michael has two brothers. His oldest brother is 1 year older than twice Michael's age when Michael was a year younger. His younger brother is 5 years old, which is a third of the age of the older brother. What is their combined age?
<bot>: How old is the oldest brother? ** The oldest brother is 15 because 3 x 5 = <<3*5=15>>15
How old is Michael? ** Michael is 8 because if 1 + (Michael's age - 1) x 2 = 15 then Michael's age = 8
What is their combined age? ** Their combined age is 28 because 5 + 15 + 8 = <<5+15+8=28>>28
#### 28
