The answer is A
Explanation
I don’t know if you need to show work but here is the answer 2(x-2)/x-3
You would have to insert the number into the variable. For example,
![3x - 27 = 18](https://tex.z-dn.net/?f=3x%20-%2027%20%3D%2018)
Then, you would isolate the x value (3x).
![3x = 18 + 27](https://tex.z-dn.net/?f=%203x%20%3D%2018%20%2B%2027)
Simplify.
![3x = 45](https://tex.z-dn.net/?f=%203x%20%3D%2045)
Finally, divide both sides by the coefficient.
![\frac{ 45}{3} = \frac{3x}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%2045%7D%7B3%7D%20%3D%20%5Cfrac%7B3x%7D%7B3%7D%20)
You end up with
The answers are:
1. c = 31.4
2. 96.2

Step-by-step explanation:
<u>Step 1: Define</u>
2x - 12 = -52
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 12 on both sides: 2x = -40
- Divide 2 on both sides: x = -20
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2(-20) - 12 = -52
- Multiply: -40 - 12 = -52
- Subtract: -52 = -52
Here we see that -52 does indeed equal -52.
∴ x = -20 is the solution to the equation.
