Question

ace's grandfather is 3 years older than Ace's grandmother. their combined age is 121 years. how old is each?​

Answer 1

Answer: Grandfather = 62

Grandmother = 59

Explanation:

1) Organize information.

• m + 3 = f

• f + m = 121
• m + (m + 3) = 121

2) Simplify.

• 2m + 3 = 121
• -3 -3

• 2m = 118

• ÷2 ÷2
• m = 59

3) Insert value of m into m + 3 = f.

• 59 + 3 = f
• 59 + 3 = 62

4) Check work.

• 59 + 62 = 121?
• Yes
