Answer:(number)=-5
Explanation:
You can use simple logic in order to solve this equation.
An equation that has infinitely many solutions will have the same exact numbers on both sides
Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true
The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.
