# Mary is two years older than Robert. The sum of their ages is 28. Write an expression for each person, write the equation for the situation and find out how old each person is.

2R = 26

R = 13

Robert is 13.

## Robert's current age --- x

Mary's current age ---- x+2

x + x+2 = 28

take it from there

## To find out how old each person is, let's write an expression for each person based on the given information.

Let's assume Robert's age as "x" years.

Since Mary is two years older than Robert, Mary's age can be expressed as "x + 2" years.

The sum of their ages is given as 28, so the equation representing the situation is:

x + (x + 2) = 28

Now, we can solve this equation to find the values of x and then calculate the ages of each person.

Combining the terms on the left side:

2x + 2 = 28

Subtracting 2 from both sides:

2x = 26

Dividing both sides by 2:

x = 13

Therefore, Robert is 13 years old.

To find Mary's age, plug in x back into the expression "x + 2":

13 + 2 = 15

Hence, Mary is 15 years old.
