Question

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: = Step 5: 1x = 2 Step 6: x = 2 Which property justifies Step 3 of his work?

Answer 1

Answer:

The identity property of addition,

Step-by-step explanation:

Because according to the identity property of addition, any number added to zero will remain the same.

Answer 2

Property justifies Step 3 of his work is property of addition.

Step-by-step explanation:

Given : Jamal uses the steps below to solve the equation $6x-4=8$.

To find : Which property justifies Step 3 of his work?

Solution :

Step 1 - Addition property, add 4 both side

$6x-4+4=8+4$

Step 2 - Solve,

$6x+0=12$

Step 3 - Identity property of addition, any number added to zero will remain the same.  

$6x=12$

Step 4 - Division property, divide both side by 6,

$\frac{6x}{6}=\frac{12}{6}$

Step 5 - Solve,

$x=\frac{2\times 6}{6}$

Step 6 - Solve,

$x=2$

Therefore, property justifies Step 3 of his work is property of addition.
