solve for n.\n-7 + 7n = 9n + 9\nn =

Explanation:

Step1: Move variable terms to one - side

Subtract (7n) from both sides: (-7 + 7n-7n=9n + 9-7n) (-7 = 2n+9)

Step2: Move constant terms to one - side

Subtract 9 from both sides: (-7-9=2n + 9-9) (-16 = 2n)

Step3: Solve for (n)

Divide both sides by 2: (n=\frac{-16}{2})

Answer:

(-8)
