Answer& Step-by-step explanation:
Proof Reason: Definition of m
In mathematics, the term "m" is often used to represent a variable or an unknown quantity. Therefore, when we encounter the symbol "m" in an equation or a problem, it is usually an indication that we are dealing with an unknown value that we need to solve for.
For example, consider the equation 2m + 3 = 9. In this equation, "m" represents the unknown value that we need to find. To solve for "m", we can follow these steps:
1. Start by isolating the variable term. In this case, the variable term is 2m. To isolate it, we can subtract 3 from both sides of the equation: 2m + 3 - 3 = 9 - 3, which simplifies to 2m = 6.
2. Next, divide both sides of the equation by the coefficient of the variable. In this case, the coefficient of "m" is 2. So, we divide both sides by 2: 2m/2 = 6/2, which simplifies to m = 3.
Therefore, the proof reason for "m" in this context is the definition of a variable or an unknown quantity. It signifies that we are looking for a value that satisfies a given equation or problem.
