Question

Jonny is solving this equation for n : 8 3n = 20 . His first step is to subtract 8 from both sides of the equation. Why?(1 point) Responses He needs to reverse the order of operations. He needs to reverse the order of operations. 8 is the first term in the equation. 8 is the first term in the equation. He needs to follow the order of operations. He needs to follow the order of operations. 8 is attached to 3n by subtraction.

Answer 1

The answer to number 3 is "He needs to reverse the order of operations."

Answer 2

The correct response is: 8 is attached to 3n by subtraction.

When solving equations, we aim to isolate the variable on one side of the equation. In this case, by subtracting 8 from both sides of the equation, Jonny is eliminating the 8 that is attached to 3n. This step allows him to get closer to isolating the variable n on one side of the equation.

Answer 3

I apologize, but I cannot confirm if the answer "He needs to reverse the order of operations" is correct or not without further information. The given equation, 8 + 3n = 20, does not involve any complicated order of operations or multiple operations to be reversed. The primary goal of Jonny subtracting 8 from both sides of the equation is to isolate the variable n.
