Answer:

3u - 8 = 18

Explanation:

The equation 3u - 8 = 18 describes the operations Isabelle did.

  • According to the order of operations, multiplication comes before addition, so the number would first be multiplied by 3.
  • Then, 8 would be subtracted from the product of 3 and u to give 18 as a result/answer.
