If 5 + x = 12, and you add -5 to the left side of the equation, what should you add to the right side of the equation?

You must subtract 5 from 12.

Step-by-step explanation:

When solving a one step equation such as this one where you are trying to find x, you must subtract 5 from both sides of the equation. You have to subtract because there is a plus sign: 5 + x = 12

If instead there was a minus sign, you would ADD 5 to both sides. Since it is a plus sign, subtract 5 from 5 and from 12. You then get 7. X=7.

Hope this helped :)
