Step-by-step explanation:
To use algebra tiles to model and solve the equation -5 = n + 2, we can represent -5 using 5 red chips and n + 2 using n blue chips and 2 green chips.
We start by placing 5 red chips on the table to represent -5.
Next, we represent n + 2 using blue and green chips. We start with n blue chips to represent n and add 2 green chips to represent 2.
To balance the equation, we need to add some red chips to the right-hand side to make the equation true. We can add 7 red chips to the right-hand side to balance the equation, since -5 + 7 = 2.
After adding 7 red chips to the right-hand side, we have the same number of red chips on both sides of the equation. This means that n = -12, since n + 2 = -12 + 2 = -10.
Therefore, the solution to the equation -5 = n + 2 is n = -12.
