1 answer:
Answer:
First part.
Explanation:
The first part is wrong. Because when you divide a number by a fraction, you will have convert it to multiply upside-down fraction but not the number that is divided :
![\frac{ {x}^{2} - 4 }{5x} \div \frac{x + 2}{x - 2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20%7Bx%7D%5E%7B2%7D%20-%204%20%7D%7B5x%7D%20%20%20%5Cdiv%20%20%5Cfrac%7Bx%20%2B%202%7D%7Bx%20-%202%7D%20)
![= \frac{(x + 2)(x - 2)}{5x} \times \frac{x - 2}{x + 2}](https://tex.z-dn.net/?f=%20%3D%20%20%20%5Cfrac%7B%28x%20%2B%202%29%28x%20-%202%29%7D%7B5x%7D%20%20%20%5Ctimes%20%20%5Cfrac%7Bx%20-%202%7D%7Bx%20%2B%202%7D%20)
![= \frac{ {(x - 2)}^{2} }{5x}](https://tex.z-dn.net/?f=%20%3D%20%20%5Cfrac%7B%20%7B%28x%20-%202%29%7D%5E%7B2%7D%20%7D%7B5x%7D%20)
e.g
(1/2)÷5 = (1/2)×(1/5)
= 1/10
e.g
2÷1/4 = 2×4
= 8

This is a 2-step equation:
![3x + 10 = 19\\\\3x = 9\\\\x = 3](https://tex.z-dn.net/?f=3x%20%2B%2010%20%3D%2019%5C%5C%5C%5C3x%20%3D%209%5C%5C%5C%5Cx%20%3D%203)
The solution is <em>x = 3</em>.
I believe it is on simplest form. But as a mixed number it would be 113/2
