I need help with this question for school tom.
"Tisha is five years older than John. Alex is three more than twice Johns age. Sara is twice as old Tisha. If John's age is represented by A, what is the algebraic representation for the other ages?"

Sometimes it helps to right separate equations for each person's age.
a + 5 = Tisha
2a + 3 = Alex
2tisha = Sara
I guess you could have that system of equations be your answer, just pick a variable for each person's name. I'm not exactly sure how you would combine that all into one equation.
Hope I helped! :)
