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+19−19=−27−19x + 19 - 19 = -27 - 19

The left side simplifies to xx because 19−19=019 - 19 = 0. The right side becomes −27−19=−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.
