Answer: s = 36

Step-by-step explanation: The key to solving multistep equations is isolating the variable. This is why I first subtracted 14 on each side. This left me with 1/3s=12. Then, to isolate "s" even more, I didvided by 1/3 on each side. This gave me s = 36 as an answer.

To divide by a fraction, use "keep change flip." Keep the first mumber, change division to multiplication, and flip the fraction. I included a picture of me doing this.

If you have any other questions, please feel free to ask :)

  • Factoring
  • Solving quadratics

Step-by-step explanation:

<u>Step 1: Set up Equation</u>

"Nine more" is + 9

"Seven times a number" is 7n

"One more" is + 1

"Square of the [same] number" is n²

7n + 9 = n² + 1

<u>Step 2: Solve for </u><em><u>n</u></em>

  1. Subtract 7n on both sides:                    9 = n² - 7n + 1
  2. Subtract 9 on both sides:                      0 = n² - 7n - 8
  3. Factor quadratic:                                    0 = (n - 8)(n + 1)
  4. Solve roots:                                            n = -1, 8
