− 4) + 5x = 9x − 10
Given ⇒ 2(x − 4) + 6x = 9x − 10
Step 1 ⇒ 2x − 8 +
6x = 9x − 10
Step 2 ⇒ 2x + 6x − 8 = 9x − 10
Step 3 ⇒ 8x − 8 = 9x − 10
Step 4 ⇒ 8x − 8x − 8 = 9x − 8x − 10
Step 5 ⇒ 0 − 8 = x − 10
Step 6 ⇒ −8 =
x − 10
Step 7 ⇒ −8 + 10 = x − 10 + 10
Step 8 ⇒ 2 = x + 0
Step 9 ⇒ 2 = x
The Additive Identity Property states that zero added to a number equals the number.
The only place where zero is added to a number is on step 8 where you see x + 0.
Step 9 shows that x + 0 = x.
Answer: Step 9

Answer:
The slope is 3/2 or 1.5
Step-by-step explanation:
To find the slope, simply divide the rise by the run. The rise of this line can be found by subtracting one y coordinate by another (it doesn't matter which by which). The run can be found by subtracting one x coordinate by another (it doesn't matter which by which).
So, let's say, for the y coordinates, I choose to subtract 3 by 0. 3 - 0 = 3. 3 is your rise.
For the x coordinates, I can choose to subtract -5 by -7. -5 - (-7) = 2. 2 is your run.
The slope is rise/run, so your answer is 3/2, which, in decimal form, is 1.5.
Hope this helped!
