## Comment on

Ages of Ebo and Atu## Can you add how to do this

## Sure thing.

Sure thing.

Let A = Atu's age 5 YEARS AGO.

This means 3A = Ebo's age 5 YEARS AGO.

That was 5 YEARS AGO. To find their ages 3 YEARS FROM NOW, we must add 8 years to the above ages.

So, A + 8 = Atu's age 3 YEARS FROM NOW

And 3A + 8 = Ebo's age 3 YEARS FROM NOW

We're told that, 3 YEARS FROM NOW, Abo's age will be TWICE that of Atu's age

In other words, 3A + 8 = 2(A + 8)

Expand: 3A + 8 = 2A + 16

Solve to get: A = 8

This means that Atu was 8 years old 5 YEARS AGO.

And it means EBO was 24 years old 5 YEARS AGO.

So, their CURRENT AGES are: Atu - 13 years old and Ebo - 29 years old

The SUM of their CURRENT ages = 13 + 29 = 42

## Is there a way to solve this

E = 3A + 10

E = 2A + 3

------using the 2nd equation------

E = 2A + 3

E - 3 = 2A

A = E/2 - 3/2 (Substitute this into the first equation)

I get E = 11

## Be careful. You made a

Be careful. You made a mistake when took the equation 3A - E = 10 rewrote it as E = 3A + 10.

Take: 3A - E = 10

Add E to both sides: 3A = E + 10

Subtract 10 from both sides: 3A - 10 = E (you have E = 3A + 10)
