-28n - 4 + 2n - 8 = 66

-26n - 12 = 66

-26n = 78

n = -3

66 = -4(7n + 1) + 2(n - 4)

  • Distribute -4 inside the parentheses.

66 = -28n - 4 + 2(n - 4)

  • Distribute 2 inside the parentheses.

66 = -28n - 4 + 2n - 8

  • Combine like terms.

66 = -26n - 12

  • Add 12 to both sides.

78 = -26n

  • Divide both sides by -26.

n = -3
