(15 x 1/n) - 3n
1. The average yards gained per play was 10.56
2. The total amount of yards recorded was 450.8 yards
You have to keep order of operations in mind.
1. Take care of the parentheses; distribute.
-3+6x-3=-20-8x
Simplified: 6x-6=-20-8x

14x=-14
3. Solve for x.
Divide by 14 on both sides.
x=-1
