Answer:2
Explanation:
You need to remember these 3 rules when working with multiplication:
Negative number x Negative number = positive number
Negative number x Positive number = Negative number
Positive Number x Positive Number = Positive Number
With that in mind, we see in this equation we are multiplying negative number x positive number = negative number
And we also know 7*2=14 so we know A = 2 and we also know (since A is a positive number) 2 will be postitive:
So the equation will look like this:
-7 x 2 = -14
Therefore A = 2
Hope this helps :D
