Question

Lisa’s age is 4 years older than three times sammy’s Age. Lisa is 28 years old let s represent sammy’s Age

Answer 1

Sammy is 8 years old

Explanation:

3s + 4 = 28 is the equation you need to use you have to get s on its own to find Sammy's age

3s + 4 = 28 subtract 4 from both sides

3s = 24 divide both sides by 3

s = 8 Sammy is 8 years old

Answer 2

Sammy's age is 8 years.

Explanation:

Let s represent Sammy’s age.

We have been given that Lisa’s age is 4 years older than three times Sammy’s age.

Three times Sammy’s age would be
`3s`.

4 years older than three times Sammy’s age would be
`3s+4`.

We are also told that Lisa is 28 years old. We can represent this information in an equation as:

`3s+4=28`

`3s+4-4=28-4`

`3s=24`

`(3s)/(3)=(24)/(3)`

`s=8`

Therefore, Sammy's age would be 8 years.
