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

B. the identity property of multiplication
In Step 3, the property used is the identity property of multiplication, which states that any number multiplied by 1 equals the original number. In this case, 6x can be simplified to x because 6 multiplied by 1 is equal to 6.
