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

Option D - Division property of equality

Explanation:

Given : Step 8 -
`(-3x)/(-3)=-(7)/(3)`

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

Solution :

Step 8 -
`(-3x)/(-3)=-(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.

`(-3x)/(-3)=-(7)/(3)`

`x=-7`

Therefore, Option D is correct.

Division property of equality

Answer 2

Answer: Option 'D' is correct.

Explanation:

Since we have given that

`-3x=7`

After Step 8 it becomes,

`(-3)/(-3)=(-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.
