What - -4 makes 12?

Answer 1

To solve the equation -4 + x = 12, we need to find the value of x. By isolating x, we can add 4 to both sides of the equation to get x = 12 + 4, which simplifies to x = 16. Therefore, the value of x that makes -4 + x equal to 12 is x = 16.

Answer 2

Note that the subtraction of a negative number is the equivalent of the addition of a positive number, therefore the equation x - -4 = 12 can be converted to

x + 4 = 12 subtract 4 from both sides and you get

x = 8

Answer 3

Oh, dude, let me break it down for you. So, what you gotta do is add 16 to -4 to get 12. It's like math magic, but not really. So, -4 + 16 = 12. Easy peasy, right?
