sergij07 [2.7K]

Answer:

2) Subtraction Property of Equality Properties

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Addition Property of Equality - Adding on both sides
  • Subtraction Property of Equality - Subtracting on both sides
  • Multiplication Property of Equality - Multiplying on both sides
  • Division Property of Equality - Dividing on both sides
  • Transitive Property - If a = b and b = c, then a = c
  • Symmetric Property - If a = b then b = a

Step-by-step explanation:

<u>Step 1: Define</u>

4m + 1 = 7 → 4m = 6

<u>Step 2: Identify</u>

We see that we <em>subtracted</em> on on both sides of the equation. Therefore, we would have to use the Subtraction Property of Equality. Therefore, 2 is our answer.
