Holly is x years old. Her brother is 4 years older than holly. Her father is 3 times older than Holly. The sum of all their ages is 104. Wright [sic] and solve an equation to find Holly's age.
-----------------
Holly = x
Brother = x+4
Father = x + 3x = 4x
------------------
Sum = 6x+4 = 104
x = 50/3 years
-----------------------------
3 times older is not the same as "3 times as old"
---
1 time older = x+x = 2x as old
2 times older = x+2x = 3x as old
etc
