Write the given sentence as an equation tim's age in 7 years will be three times what it was 19 years ago

We have to translate the given sentence into an equation.

Let the present age of Tim is x years.
His age in 7 years can be written as (x + 7) years
His age 19 years ago can be written as (x – 19) years

We are given that Tim’s age in 7 years will be 3 times his age 19 years ago.

So, we can write the equation as:

Tim’s age in 7 years = 3 x (Tim’s age 19 years ago)

x + 7 = 3 ( x – 19 )

Using this equation, the present age of Tim can be found.
