Answer 1

Here x Is the age of Laura. Therefore option A. is the correct answer.
That is x-3 years.

Answer 2

Jeri is x - 3 years old. Hence option (a.) x - 3 yrs old is the correct option.

Given:

Jeri is 3 years younger than Laura.

The age of Laura is equal to x.

To Find:

The age of Jeri.

Solution:

Let the age of Jeri be 'y'.

According to the question, the age of Laura is equal to x.

→ Jeri is 3 years younger than Laura, this implies that the age of Jeri is 3 years smaller than the age of Laura.

→ This means that the value of y is 3 less than the value of 'x'.

→ On Converting the above statement into an equation, we get:

                                          ∴ y = x - 3

The value of 'y' comes out to be equal to (x - 3).

So we can conclude that the age of Jeri is x - 3 years.

Therefore Jeri is x - 3 years old. Hence option (a.) x - 3 yrs old is the correct option.
