Answer:
Step-by-step explanation:
First of all it should be like fractions
So -2/3 becomes -10/15

-9/15 is greater than -10/15
-3/5 is greater than -2/3
To solve this we need to use this formula:
![a(b + c) = ab + ac](https://tex.z-dn.net/?f=a%28b%20%2B%20c%29%20%3D%20ab%20%2B%20ac)
![5(3x + 2) - 2(4x - 1) = 15x + 10 - 8x + 2 = \\ = 7x + 12](https://tex.z-dn.net/?f=5%283x%20%2B%202%29%20-%202%284x%20-%201%29%20%3D%2015x%20%2B%2010%20-%208x%20%2B%202%20%3D%20%20%5C%5C%20%20%3D%207x%20%2B%2012)
