Answer:
This isn't a real question... but i can explain what you gave. 12/14 is less than 1, so it is less than 9.
As an inequality it would be: -1 + 5 * 6 < 29
Consider the given equation:
![2.5(10-x)+10 = 72 -1.5(5x+12)](https://tex.z-dn.net/?f=2.5%2810-x%29%2B10%20%3D%2072%20-1.5%285x%2B12%29)
Applying distributive property, ![a(b+c) = ab + ac](https://tex.z-dn.net/?f=a%28b%2Bc%29%20%3D%20ab%20%2B%20ac)
![(2.5 \times 10) + (2.5 \times -x) + 10 = 72 - (1.5 \times 5x) + (-1.5 \times 12)](https://tex.z-dn.net/?f=%282.5%20%5Ctimes%2010%29%20%2B%20%282.5%20%5Ctimes%20-x%29%20%2B%2010%20%3D%2072%20-%20%281.5%20%5Ctimes%205x%29%20%2B%20%28-1.5%20%5Ctimes%2012%29)
![25 - 2.5x + 10 = 72 - 7.5x - 18](https://tex.z-dn.net/?f=25%20-%202.5x%20%2B%2010%20%3D%2072%20-%207.5x%20-%2018)
Adding and subtracting like terms, we get
![35-2.5x = 54 - 7.5x](https://tex.z-dn.net/?f=35-2.5x%20%3D%2054%20-%207.5x)
![35 - 54 = 2.5x -7.5x](https://tex.z-dn.net/?f=35%20-%2054%20%3D%202.5x%20-7.5x)
![-19 = -5x](https://tex.z-dn.net/?f=-19%20%3D%20-5x)
![x = \frac{19}{5}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B19%7D%7B5%7D)
x = 3.8
So, the value of 'x' in the given equation is 3.8
15,17,19 are all odd numbers and add to 51
