The absolute value equation is:
|x + 1.3| = x + 1.3
The absolute value equation that we have is:
|x - b| = c
And we want that the solution set is all the numbers larger than -1.3
Now, remember that:
| something| ≥ 0.
So the absolute value is always equal or larger than zero.
So, for example, the equation:
|x| = x
Only is true if x ≥ 0, because if x is smaller than zero, for example x = -2, we would have:
|-2| = -2
2 = -2
Which is false.
Now we want to have solutions larger than -1.3 instead of larger than zero, so we can write:
|x + 1.3| = x + 1.3
The solution of this equation is the given set.
