Solving x+19=27x + 19 = -27 Using the Subtraction Property

To solve the equation x+19=27x + 19 = -27, the objective is to isolate xx by reversing the addition of 1919. Apply the Subtraction Property of Equality by subtracting 1919 from both sides:

x+1919=2719x + 19 - 19 = -27 - 19

The left side simplifies to xx because 1919=019 - 19 = 0. The right side becomes 2719=46-27 - 19 = -46. Therefore, x=46x = -46.

To check, substitute 46-46 into the original equation: 46+19=27-46 + 19 = -27, which simplifies to 27=27-27 = -27. This true statement confirms that x=46x = -46 is the correct solution.
