Answer 1

• Lisa is 6 years old.

We are given that Lisa's age plus Sean's age is 17 years and Sean is 11 years old .

We need to find the age of Lisa.

Let's assume age of Lisa be x years.

A/q Lisa's age plus Sean's age is 17

`\longrightarrow \: x + Sean's \: age = 17 \\ \\ \longrightarrow \: x + 11 = 17 \\ \\ \longrightarrow \: x = 17 - 11 \\ \\ \longrightarrow \: x = 6 \\ \\`

Hence, Lisa is 6 years old.
