For this case we must find the value of the variable "x" of the following equation:
![\frac {2} {3} (x + 7) = 10](https://tex.z-dn.net/?f=%5Cfrac%20%7B2%7D%20%7B3%7D%20%28x%20%2B%207%29%20%3D%2010)
We multiply by 3 on both sides of the equation:
![2 (x + 7) = 30](https://tex.z-dn.net/?f=2%20%28x%20%2B%207%29%20%3D%2030)
We divide between 2 on both sides of the equation:
![(x + 7) = 15\\x + 7 = 15](https://tex.z-dn.net/?f=%28x%20%2B%207%29%20%3D%2015%5C%5Cx%20%2B%207%20%3D%2015)
We subtract 7 on both sides of the equation:
![x = 8](https://tex.z-dn.net/?f=x%20%3D%208)
Answer:
