Work Step by Step

We start with the given equation: $7=-2(4n-4.5)$ We apply the distributive property to simplify the right side of the equation: $7=-8n+9$ We subtract $9$ from both sides of the equation: $$7-9=-8n+9-9$$$$-2=-8n$$ We divide by $-8$ on each side of the equation: $$\frac{-2}{-8}=\frac{-8n}{-8}$$$$\frac{1}{4}=n$$
