Solving $n - 0.63 = -4.2$ Using the Addition Property

Solving the equation $n - 0.63 = -4.2$ involves isolating the variable $n$ and working with decimals. First, apply the Addition Property of Equality by adding ${0.63}$ to both sides, which gives $n - 0.63 + 0.63 = -4.2 + 0.63$ . This simplifies the left side to $n$ . Adding the decimals on the right side yields $n = -3.57$ . To check the solution, substitute ${-3.57}$ back into the original equation for $n$ , which gives $-3.57 - 0.63 = -4.2$ . Subtracting on the left side produces $-4.2 = -4.2$ , a true statement confirming that $n = -3.57$ is the correct solution.
