Answer:
The identity property of addition
Step-by-step 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.
