Question

Let x be Bob's age. Heather is 5 years younger than Bob. Write an expression for Heather's age.

Answer 1

x-5

Explanation:

since we don't know bob's age, x will represent it. we know that heather is 5 years YOUNGER than bob.

x (bob's age) - 5 (because that's how many years heather is younger than bob is)
