Answer & Step-by-step explanation:

To start the question, you could set up an equation to explain that -7 is being moved x units to -3

-7 + x = -3

Next you have to find x

-7 + x - (-7) = -3 - (-7)

x = 4

Now you substitute x for 4 in the original equation

-7 + 4 = -3

Hope this helped!!!

Answer:

-7+4=-3

Explanation:

Think of it as adding head to cold (cold being negative numbers). You are adding four "heats" to seven which makes it hotter. The hotter something gets the closer to positive numbers it is. . . so when adding four things if heat to 7 it gets hotter by four therefore it's now at -3.

sorry if that didn't make sense
