Answer:

The number is -6.

Explanation:

Let x = the unknown number

"the sum of a number and four" = n + 4

"Six times the sum of a number and four" = 6(n + 4)

"Six times the sum of a number and four is -12." is the equation

6(n + 4) = -12

Divide both sides by 6.

n + 4 = -2

Subtract 4 from both sides.

n = -6
