Ineed with these 2 questions. i will give brainleist! number 1 tj, max, and misha are all the same age. the sum of their ages is s years. how old was tj eight years ago? number 2 alex is 3 times as old as he was 2 years ago. how old is he now? !

TJ, Max, and Misha are all the same age. The sum of their ages is s years. How old was TJ eight years ago?

Sum up the ages of these three guys:  t+x+m=s

TJ's present age is s/3.  Eight years ago his age was s/3 - 8.

Number 2

Alex is 3 times as old as he was 2 years ago. How old is he now?  Let his age NOW be a.    His age, a, right now, is 3(a-2), or 3a-6.

Solve a = 3a - 6 for a:  6 = 2a; a = 3.  Alex is 3 years old now.

Strange problem!  But a=3 years is a valid solution.

2 years ago, Alex was 1 year old.  Three times that is 3 (his current age).
