Question

A number decreased by twelve is twice the opposite of ten. Find the number.

Answer 1

Okay so the opposite of 10 is -10
So 2-12=-10 and negative ten is the opposite to positive ten.
Does that make sense?

Answer 2

-8

Explanation:

Let n = the number.

A number decreased by twelve is twice the opposite of ten.

n - 12 = 2 * (-10)

n - 12 = -20

n = -8
