Answer: The solution of the equation is x = 48. The equation is 20 = x - 28.
Explanation:
-20 is like having -20 dollars, and you want to know how much you have to add to it to get to 28 dollars. So we add 20 to -28 and we get the number x = 48, so 48 dollars is what we need to add to -20 dollars to get to 28 dollars.
