4 0

Answer:

A 3

Step-by-step explanation:

Let n = the number

a number decreased by 12

n-12

This is equal to 3 times the opposite =

3 times the opposite

3*(-n)

-3n

Setting the two parts equal

n-12 = -3n

Subtract n from each side

n-n-12 = -3n-n

-12 = -4n

Divide by -4

-12/-4 = -4n/-4

3 =n
