Question

Write an algebraic equation for each question below and then solve the equation.

5. Jerry sold 50 rare coins from his collection. He now has 225 rare coins. How many coins were originally in his collection?

Answer 1

Let the original number of rara coins that Jerry had back then be x.

now if he sold 50 rare coins, the coins left will be x - 50

• x - 50 = 225

• x = 225 + 50

• x = 275
