Answer:

19.8x - 11.1y

Step-by-step explanation:

Given information:

  • Gain 25x yards
  • Gain 0.9y yards
  • Lose 12y yards
  • Lose 5.2x yards

"Gain" means to add the value.

"Lose" means to subtract the value.

Therefore, net yardage is:

⇒ 25x + 0.9y - 12y - 5.2x

Collect like terms:

⇒ 25x - 5.2x + 0.9y - 12y

Factor out the common variables x and y:

⇒ x(25 - 5.2) + y(0.9 - 12)

Carry out the operations in the parentheses:

⇒ x(19.8) + y(-11.1)

Therefore, the net yardage is  19.8x - 11.1y
