Answer: If two pair is parallel then it has no solution.
Step-by-step explanation:
Since we have given that
Let the number of gained yards by each player be y
For the case of Brayden:
Equation will be

For the case of Howard :
Equation will be

For the case of Vincent :

Since First two equations are parallel so it has no solution.
Reason:

Hence, if two pair is parallel then it has no solution.
{ 3-y=2x
{ x+1/2y=3/2
{ -y=2x-3
{ 1/2y=3/2-x
{ y=-2x+3
{ y=3-2x
-2x+3=3-2x
(x,y) = (x,-2x+3)
18 - 7x = -20.52.5 = 7xx = 5/14 (c)
