Question

This is on my math book. Jada's neighbor said, "my age is the difference between twice my age in 4 years and twice my age 4 years ago." How old is Jada's neighbor.

Answer 1

Answer:

Jada’s neighbor is 16 years of age

Step-by-step explanation:

In this question, we are interested in calculating the age of Jada’s neighbor, given the information in the question.

Let the present age of the neighbor be x years

Her age in 4 years will be x + 4 years old

Her age 4 years ago was x -4 years old

Now, the difference between twice her age in 4 years minus twice her age 4 years ago is her present age.

mathematically that means;

2(x+ 4) - 2(x -4 ) = x

2x + 8 - 2x +8 = x

16-0 = x

x = 16 years
