How do instead of x is equal to the life of Mark
Bob Mark older than 7 years equals x + 7
Bryan Bob older than 2 years of (x + 7) +2 = x + 9
, and the age of the three possible combinations of 61 years.
The equation is as follows. x + (x + 7) + (x + 9) = 61
+ 16 = 61 would have 3x
3x + 16-16 = 61 to 16
3x = 45
x = 15
, so 15-year-old mark of x is equal to
Bob age of x + 7. 15 + 7 equals 22 years of
age, Brian equal to x + 9 = 15 + 9 equals 24 years on the 15-year-old Mark was 22 years old Bob Bryan is 24 years old.
