Let x be the original position.
After the first play they gain 9 yards. The position can be represented by
x + 9
After the second play they lose 22 yards. The position can be represented by
x + 9 - 22 = x - 13
Therefore, in total they lost 13 yards.
-x - 5 = -11
add 5 to both sides
-x - 5 + 5 = -11 + 5
-x = -6
x = 6
5x+30- 2x+9
3x+39 is the expression.

Answer:
a(n) = 37 - 5(n -1)
Step-by-step explanation:
Notice that each new term is obtained by subtracting 5 from the previous term. Thus, this is an arithmetic sequence with common difference -5 and first term 37.
The explicit formula for the nth term is a(n) = a(1) - 5(n - 1) = 37 - 5(n -1)
