**Answer:**

D. The subtraction property of equality was not applied to solve this equation.

**Step-by-step explanation:**

<u>Step 1</u>: Given

<u>Step 2</u>: Addition Property of Equality

(add 7 to both sides)

<u>Step 3</u>: Simplify

<u>Step 4</u>: Multiplication Property of Equality

(multiply both sides by 2)

<u>Step 5</u>: Simplify

**Answer:**

4x12=48

**Step-by-step explanation:**

1 car=4 wheels

12cars= 48 wheels

**Answer:**

**x** = **-1**

**Step-by-step explanation:**

First, add **x** to both sides.

-2x-6-x+x=-x-4x-8+x

-----------------------------------

Next, Refine it.

-2x - 6 = -4x - 8

--------------------------------------

Now, add 6 to both sides.

-2x - 6 + 6 = -4x - 8 + 6

--------------------------------------

Now we Simplify.

-2x = -4x - 2

---------------------------------------

Add 4x to both sides.

-2x + 4x = -4x - 2 + 4x

----------------------------------------

Simplify again.

2x = -2

-----------------------------------------

Divide both sides by 2.

2x/**2** = -2/**2**

------------------------------------------

And we're almost finish! Just need to simplify.

x = -1.

For #32, the answer is the third one because you mixed up your x and y values, you were on the right track though

#33 is the last one

A number line includes all the numbers in between the ones marked on it, for example if a line starts on point 3 and ends on point 7 the line includes all the numbers between 3 and 7 (3.14, 3 1/2, 6 3/4, 6.33)
