a) Write an expression for Ben's age and Alice's age in terms of x.​

Answer 1

a)

Amy's age is x.

• Ben's age is 2 more than Amy's age.

∴ Ben's age = x + 2

• Alice's age is 6 less than Amy's age.

∴ Alice's age = x - 6

Answer 2

Explanation:

Amy = x years

Ben = x + 2 (years)

Alice = x - 6 (years)
