Now:
Marcus ---- x
John ------ x+10
5 years from now:
John's age = x+15
5 years ago:
Marcus = x-5
3(x+15) = x-5
that would give you the silly answer of x = -25
checking
now Marcus is -25
John is -15
5 years from now, John is -10
and 5 years ago Marcus was -30
sure enough 3 times John's age (or -30) equals Marcus' age .
Mathematically it works, but in reality this question is bogus.
Check your typing or else tell your teacher that the question makes no sense.
John is now 10 years older than Marcus. Three times Johns age 5 years from now will be the same age as Marcus age 5 years ago. Write the equation and solve
