Answer 1

Given:

✰ Age of Sam = 11 years

✰ Age of Sam's uncle = 59 years

To find:

✠ How many years ago was Sam's uncle 7 times as old as Sam?

Solution:

Let's understand the concept first!

• First we will assume that x years ago Sam's uncle was 7 times as old as Sam, which means that x will be subtracted from both their ages, that is the age of Sam and the age of his uncle.
• After that we know x years ago Sam's uncle was 7 times as old as Sam which means 7 will be multiplied by Sam's age.
• Thus forming an adequate equation and doing the required calculations, we will find the value of x that is is number of years ago when Sam's uncle was 7 times as old as Sam.

Let's find out...✧

Let x years ago was Sam's uncle 7 times as old as Sam.

⤳Age of Sam = 11 years - x years

⤳Age of Sam's uncle = 59 years - x years

According to the question,

➤ 59 - x = 7( 11 - x )

➤ 59 - x = 77 - 7x

➤ - x + 7x = 77 - 59

➤ - x + 7x = 77 - 59

➤ 6x = 18

➤ x = 18/6

➤ x = 3

∴ 3 years ago was Sam's uncle 7 times as old as Sam.
