Question 7: NAME_1 has just turned 39.  3 years ago, he was twice as old as NAME_2 will be in 6 years.  If NAME_2' older brother is 4 years older than NAME_2, how old is NAME_2' older brother?
Answer: Let's think step by step.

Sure, let's break down the problem into smaller parts and solve it step by step.

Let's start with the first piece of information:

\"NAME_1 has just turned 39.\"

This means that NAME_1's current age is 39.

Now, let's move on to the second piece of information:

\"3 years ago, he was twice as old as NAME_2 will be in 6 years.\"

Let's break this down further. Three years ago, NAME_1's age was:

39 - 3 = 36

And in six years, NAME_2' age will be:

x + 6 (where x is NAME_2' current age)

So, three years ago, NAME_1 was twice as old as NAME_2 will be in six years. Mathematically, we can represent this as:

36 = 2(x + 6)

Simplifying this equation, we get:

36 = 2x + 12

Subtracting 12 from both sides, we get:

24 = 2x

Dividing both sides by 2, we get:

x = 12

So, NAME_2' current age is 12.

Finally, let's move on to the last piece of information:

\"If NAME_2' older brother is 4 years older than NAME_2, how old is NAME_2' older brother?\"

Since NAME_2' current age is 12, his older brother's age is:

12 + 4 = 16

Therefore, NAME_2' older brother is 16 years old.

Question 8: NAME_3 is currently 11 years old and his older brother is 20 years old. How old will NAME_3 be when his older brother is three times as old as NAME_3 is now?
Answer: Let's think step by step.

Sure, let's break down the problem together.

We know that NAME_3 is currently 11 years old and his older brother is 20 years old. Let's represent their ages as T for NAME_3 and B for his brother.

So, we have:

T = 11 (NAME_3's current age)
B = 20 (his brother's current age)

Now we need to figure out when NAME_3's older brother will be three times as old as NAME_3 is now. Let's represent the number of years from now as x.

So, when NAME_3's older brother is three times as old as NAME_3 is now, we can write:

B + x = 3(T + x)

We can simplify this equation by distributing the 3:

B + x = 3T + 3x

Next, we can substitute the values we know for B and T:

20 + x = 3(11 + x)

Now we can solve for x to find out how many years from now NAME_3's older brother will be three times as old as NAME_3 is now:

20 + x = 33 + 3x

2x = 13

x = 6.5

So, in 6.5 years, NAME_3's older brother will be three times as old as NAME_3 is now.

To find out how old NAME_3 will be in 6.5 years, we can add x to his current age:

T + x = 11 + 6.5 = 17.5

Therefore, NAME_3 will be 17. Make sure your entire response is wrapped in JSON format.
