Father is 46 y.o.

In how many more years Y will 46+Y be 3(14+Y) ?

Here first is another presentation of the solution provided by the other tutor.

Let y be the number of years from now that her father's age will be 3 times her age.

Their current ages are 14 and 46; y years from now their ages will be 14+y and 46+y.

We want to know when 46+y will be 3 times (14+y):

ANSWER: Her father's age will be 3 times her age in 2 years.

CHECK: 14+2=16; 46+2=48; 48=3*16

Here is a very different algebraic approach to solving the problem.

The difference between their ages is 46-14=32 years.

When the father is 3 times as old, their ages can be represented by x and 3x; the difference between their ages will be 3x-x=2x.

But the difference between their ages is 32 years. So 2x=32; x=16.

The father will be 3 times as old as his daughter when their ages are x=16 and 3x=48. Since their ages are currently 14 and 46, that will be 2 years from now.

All the words of explanation make this sound like a longer and slower approach to solving the problem. However, this method of solving the problem can be done mentally in far less time than writing and solving an equation.
