2. THE TIGERS FOOTBALL TEAM GAINED 12 YARDS ON THEIR SECOND PLAY. ON THEIR THRID PLAY, THEY LOST 24 YARDS. ON THEIR FOURTH PLAY, THEY GAINED 31 YARDS AND WERE STOPPED AT THEIR 42-YARD LINE. AT WHAT YARD LINE WERE THEY AFTER THE FIRST PLAY?

Answer by vleith(2983) (Show Source): You can put this solution on YOUR website!
Let s be the number susan had
L = s - 6
C = L + 8 = (s-6) + 8 = s + 2
M = c -5 = (s+2)-5 = s - 3
M = 5
So M = 5 = S - 3
S = 8
2) Let X be the starting point after the first play
s = x + 12
t = s - 24 = (x+12) - 24 = x - 12
f = t + 31 = (x-12) + 31 = x + 19
After f they were at their own 42. Which was x + 19 more than after the first play.
42 = x + 19
42 - 19 = x
23 = x
