Question

Indicate which property is illustrated in step 8. A. Subtraction property of equality B. Simplification C. Distributive property D. Division property of equality
step 8: -3x/-3 = -7/3

Answer 1

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

$-3x=7$

After Step 8 it becomes,

$\dfrac{-3}{-3}=\dfrac{-7}{3}$

It indicated the Division property of equality.

To find the value of x, we need to divide the left hand side and right hand side by -3.

So, this property is known as "Division property of equality":

Hence, Option 'D' is correct.

Answer 2

Answer:

Option D -  Division property of equality

Step-by-step explanation:

Given : Step 8 - $\frac{-3x}{-3}=-\frac{7}{3}$

To find : Indicate which property is illustrated in step 8 ?

Solution :

Step 8 - $\frac{-3x}{-3}=-\frac{7}{3}$

In step 8 we have seen that -3 is divided both side,

So, The division property of equality is applied to get the result.

$\frac{-3x}{-3}=-\frac{7}{3}$

$x=-7$

Therefore, Option D is correct.

Division property of equality
