when Mary was born, her mother was 28 years old. At present, Mary's age is 4 less than one-third of her mother's age. Find the present age of Mary
Chatgpt 答案係68:
Let's assume the present age of Mary is m years and the present age of her mother is M years.
According to the given information, when Mary was born, her mother was 28 years old. This means there is a 28-year age difference between Mary and her mother. We can express this as:
M - m = 28   ----(1)
The second piece of information states that Mary's age is 4 less than one-third of her mother's age. Mathematically, we can express this as:
m = (1/3)M - 4   ----(2)
Now we have a system of equations (equation 1 and equation 2) that we can solve to find the values of M and m.
Substituting equation 2 into equation 1, we get:
(1/3)M - 4 = 28
Multiplying both sides of the equation by 3 to eliminate the fraction, we have:
M - 12 = 84
Adding 12 to both sides of the equation, we get:
M = 96
Substituting the value of M back into equation 1, we have:
96 - m = 28
Subtracting 96 from both sides of the equation, we get:
-m = -68
Multiplying both sides of the equation by -1 to solve for m, we have:
m = 68
Therefore, the present age of Mary is 68 years.

AI理解冇錯，可能係算式令佢計法錯？

d fake gpt 同無plugin就真係垃圾.

You:

wolfram: 請解答以下數學題
when Mary was born, her mother was 28 years old. At present, Mary's age is 4 less than one-third of her mother's age. Find the present age of Mary

------------------

ChatGPT:

It seems there was an issue with the query format. Let me rephrase it and try again.

We need to solve the system of equations where Mary's age is 4 less than one-third of her mother's age, and when Mary was born, her mother was 28 years old. Let's denote Mary's age as
𝑀
M and her mother's age as
𝑀
𝑚
M
m

. The equations are:

𝑀
=
1
3
𝑀
𝑚

4
M=
3
1

M
m

−4
𝑀
𝑚
=
𝑀
+
28
M
m

=M+28

Let me re-submit this to Wolfram|Alpha for a solution.

It appears that Wolfram|Alpha misinterpreted the variables �M and ��Mm​ as units of measurement (meters and megameters) rather than as symbols representing ages. I'll adjust the query to clarify that these are variables representing ages and try again.
Used [b]Wolfram[/b]

The solution to the problem is that Mary's present age is 8 years old.
This was determined by solving the equation �=13×(�+28)−4M=31​×(M+28)−4, where �M represents Mary's age.
