Answer 1

Answer:

Solving age problems we generally will be comparing the age of two people ... Solve the equation for x, use the solution to answer the question ... Carmen is 12 years older than David

Answer 2

Answer:

Let x be the Maria's present age.

Then the Stell's age is (x+4), according to the problem's description.

In 12 years, Stella's age will be ((x+4)+12) = (x+16) years.

According to the problem's description, we can write this equation

x + 16 = 2x.

It implies

16 = 2x - x

x = 16.

ANSWER. Maria is 16 years old. It is her present age.
