Question

John is 4 years younger than twice Michael's age. Michael is John's younger brother. John is 18 years old. How old is Michael? Choose the equation that represents the situation.

Answer 1

This is the answer considering that x represent john’s age and y represent Michael’s age

Answer 2

18=2m-4

Explanation:

18 is the age of John. M represents the age of Michael. John is older than Michael so instead of 18=4-2m it is 18=2m-4. If you do 8=4-2m it will be inccorect because it will give you a negative. Michael is 11 years old.
