Respuesta :
We are trying to find the number that when added to 19, gives us less than 42. We can set up this simple inequality:
19 + x < 42
Now, subtract 19 from both sides:
x < 23
Our number can be anything less than 23.
19 + x < 42
Now, subtract 19 from both sides:
x < 23
Our number can be anything less than 23.
