Shawna, Dexter, and Tilana are solving the equation Negative 2.5 (5 minus n) + 2 = 15.
Shawna says, βI can begin by dividing each side of the equation by β2.5 to get 5 minus n minus StartFraction 2 over 2.5 EndFraction = Negative StartFraction 15 over 2.5 EndFraction.β
Dexter says, βI can begin by distributing Negative 2.5 to get Negative 12.5 + 2.5 n + 2 = 15.β
Tilana says, βI can begin by multiplying each side of the equation by Negative StartFraction 1 over 2.5 EndFraction to get 5 minus n minus 0.8 = negative 6.β
