You can put this solution on YOUR website! Tyrone is twice as old as his daughter. in six years Tyrone's age will be three times what his daughter's age was six years ago. how old are they at present?
:
The equation for the statements,"Tyrone is twice as old as his daughter."
t = 2d
:
and the equation for the statement:
"in six years Tyrone's age will be three time what his daughter's age was six years ago."
t + 6 = 3(d-6)
Simplify
t + 6 = 3d - 18
t = 3d - 18 - 6
t = 3d - 24
:
how old are they at present?
:
We know t = 2d so we have:
2d = 3d - 24
2d - 3d = -24
-d = -24
d = 24 is daughter's age
Then
2(24) = 48 is T's age
:
:
Check solutions in the statement:
in six years Tyrone's age will be three time what his daughter's age was six years ago."
48 + 6 = 3(24 - 6)
54 = 3(18); confirms our solution

That wasn't so hard, was it?
