For this case we must resolve the following inequality:
![x-7 <-12](https://img.qammunity.org/2020/formulas/mathematics/middle-school/naek20lige9e9n2ce9kdme5xb1b00udeyw.png)
Adding 7 to both sides of the inequality:
![x <-12 + 7](https://img.qammunity.org/2020/formulas/mathematics/middle-school/j859m33ojw7r9j6k85ce47tjhlleruiroa.png)
Different signs are subtracted and the major sign is placed.
![x <-5](https://img.qammunity.org/2020/formulas/mathematics/middle-school/1yqz3jzo99m3le6salnb3nz6deymg240xr.png)
Thus, the solution is given by all the values of "x" less than -5.
The solution set is: (-∞, - 5)
Answer:
