Answer 2

Answer:

Let’s solve this through process of elimination; Let’s rewrite our answers

3+(-7)

-3+(-7)

-3+7

3+7

According to the question, three was not a negative number. So we can eliminate all the options which refer to 3 as negative.

3+(-7)

3+7

Think of a number line. We know that 0 is in the center. Anything to the left of it is negative, and to the right is positive.

When the equation says “7 units to the left” they are referring to subtraction rather than addition. Let’s get rid of the option that has addition.

3+(-7)

This is your answer! Hope this helps comment below for more questions :)
