Aa = -65
Ba = -9
Ca = -19
Da = 18
Answer & Solution
Correct answer: B. a = -9
1. To isolate a, add 28 to both sides using the Addition Property of Equality.
2. a minus 28 plus 28 equals -37 plus 28.
3. Simplify both sides: a equals -9.
4. Check: -9 minus 28 equals -37, which matches the original equation.
