Jamal uses the steps below to solve the equation 6x – 4 = 8. Step 1: 6x – 4 + 4 = 8 + 4 Step 2: 6x + 0 = 12 Step 3: 6x = 12 Step 4: StartFraction 6 x Over 6 EndFraction = StartFraction 12 Over 6 EndFraction Step 5: 1x = 2 Step 6: x = 2 Which property justifies Step 3 of his work? the addition property of equality the identity property of addition the multiplication property of equality the identity property of multiplication

Answer:

The identity property of addition

Explanation:

Jamal uses the steps below to solve the equation 6x – 4 = 8.

Step 1: 6x – 4 + 4 = 8 + 4( Addition step of equality)

Step 2: 6x + 0 = 12

Step 3: 6x = 12 (Identity property of Addition)

Step 4: StartFraction 6 x Over 6 EndFraction = StartFraction 12 Over 6 EndFraction

Step 5: 1x = 2

Step 6: x = 2

The that property justifies Step 3 of his work is known as the identity property of addition.

The identity property of addition can be defined as when a given number x is added to zero, the result is we obtained x which is the given number itself.
