Why is the task worded so strangely?
My interpretation and a suggested solution:
Task: Marc, Stefan and Till play basketball as a team. Marc scored twice as many points as Stefan in yesterday's game. Stefan scored 8 points more than Till. Overall, the three scored 36 points for their team. Calculate the points scored by Marc, Stefan and Till.
Variables:
Marc's points m
Stefan's points s
Till's points t
Equations():
m=2s (i)
s=t+8 (ii) -> t= s-8
36 = m + s +t (iii)
Insert (i),(ii) in (iii):
(iii) 36 = 2s + s + (s-8) = 4s-8 -> 4s=44 -> s=11
Insert s=11 in (i) -> m=2*11 =22 and in (ii) -> t= 11-8=3
