Split Into Groups

Example 1 Yuri is twice as old as Zack. Four years from now, the sum of their ages will be 23.

Example 2 Mandy has 11 coins in dimes and quarters. The value of her coins is $2.15. How many dimes does she have?

Example 3 When the digits of a two-digit number are reversed, the new number is 45 less than the original number. The sum of the digits is 7. What is the original number?

Try This 1. The sum of the digits of a two-digit number is 17. When the digits are reversed, the new number is 9 more than the original number. What is the original number? 2. Vic has 14 coins in nickels and quarters. The value of his coins is $1.70. How many quarters does he have? 3. Grace is 8 years older than her brother Sam. The sum of their ages is 24. How old is Grace?
