Question

What property of equality is displayed in step 3 in the solving of 9m+4−7m=5m+73 ?

Step 1:

9m+4−7m=5m+73

9m−7m+4=5m+73

Step 2:

2m+4=5m+73

3(2m+4)=(5m+73)3

Step 3:

6m+12=5m+7

6m+12−12=5m+7−12

Step 4:

6m=5m−5

6m−5m=5m−5m−5

m=−5

Answer 1

The property of equality displayed in step 3 of the given equation is the **Subtraction Property of Equality**. This property states that if you subtract the same value from both sides of an equation, the two sides remain equal. In this case, \(6m + 12 - 12 = 5m + 7 - 12\) shows that 12 was subtracted from both sides of the equation.
