Answer: +21
Step-by-step explanation:
Based on the information given, we are informed that at first down, a football team lost 16 yd and they after two downs, the team had an overall gain of 5 yd.
The number of yards that were gained on second down can be represented by x. We can then form the question as an equation as:
x - 16 = 5
x = 5 + 16
x = 21
The team gained 21 yards.
