Q. Solve for nn.\newline−9n+19n−17=13-9n + 19n - 17 = 13\newlinen=n = __
  1. Combine like terms: Combine like terms on the left side of the equation.\newline−9n+19n−17=13-9n + 19n - 17 = 13\newline(19n−9n)−17=13(19n - 9n) - 17 = 13\newline10n−17=1310n - 17 = 13
  2. Add 1717: Add 1717 to both sides to isolate the term with the variable nn.\newline10n−17+17=13+1710n - 17 + 17 = 13 + 17\newline10n=3010n = 30
  3. Divide by 1010: Divide both sides by 1010 to solve for nn.10n10=3010\frac{10n}{10} = \frac{30}{10}n=3n = 3
