Answer:
The number is 6
Step-by-step explanation:
We let the number be x. If we subtract -2 from x we obtain the following result;
x - (-2)
This can be simplified to yield the following result;
x - (-2) = x + 2
we use the rule that negative multiplied by negative yields a positive sign.
We are further informed that the result of the above operation is 8, therefore;
x + 2 = 8
Solving for x yields;
x = 8 -2
x = 6
