Answer:
James is 19 years old.Mindy is 21 years old. Laura is 63 years old.
Explanation:
Let James age be x.
Then Mindy will be x + 2
Then Laura will be 3(x + 2)
If they sum up, the total age is 103 years.
3(x + 2) + x + 2 + x = 103
3x + 6 + x + 2 + x = 103
5x + 8 = 103
5x = 95
x = 19 years
James is 19 years old.
Then Mindy is (x + 2)
→ 19 + 2
→ 21 years old
Then Laura shall be 3(x + 2)
→ 3(19 + 2)
→ 3(21)
→ 63 years old
