Question

What property of equality is shown in this step of solving the equation?



6m+12=5m+7
6m+12−12=5m+7−12

Answer 1

The property of equality shown in this step is the **Subtraction Property of Equality**. This property states that if you subtract the same number from both sides of an equation, the two sides remain equal. In this case, \(12\) is subtracted from both sides of the equation \(6m + 12 = 5m + 7\).
