When asked how old she was Mary replied in two years I will be twice as old as I was five years ago
How is this English?
m+2 = 2(m-5)
Mary is 12
To solve this problem, we can set up an equation based on the information given. Let's assume Mary's current age is x.
According to the problem, in two years, Mary will be (x + 2) years old. Five years ago, Mary was (x - 5) years old.
The problem states that in two years, Mary will be twice as old as she was five years ago. So, we can set up the equation:
x + 2 = 2 * (x - 5)
Now, let's solve this equation step by step to find Mary's current age.
Expanding the right side:
x + 2 = 2x - 10
Moving all the x terms to one side:
x - 2x = -10 - 2
Simplifying:
-1x = -12
Dividing both sides by -1:
x = 12
Therefore, Mary's current age is 12 years old.
