Question

Share is 4 times as old as Marcos. If the sum of their age is 45, which equation could best be used to find their ages?

Answer 1

4x+x =45

Explanation:

x would be marcos, since we do not know his age, and share is 4x that amount, so you would have 4x(shares age) plus x(marcos age) to get your answer.

Answer 2

5x = 45

Explanation:

x represents marcos

4x represents Share

5x = 45

x = 9

4x = 36

Share is 36 and Marcos is 9
