Question

This equation needs to be solved

Answer 1

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

-26n - 12 = 66

-26n = 78

n = -3

Answer 2

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
