We'll have to solve the double
inequality:
-5>x-3>5
We'll
solve the first, left, inequality and we'll apply the symmetric
formula:
x - 3 <
-5
We'll add 3 both sides:
x
< -5 + 3
x <
-2
x belongs to the interval of values: (-infinite,
-2)
We'll solve the right
inequality:
x - 3 >
5
We'll add 3 both sides:
x
> 5 + 3
x > 8
x
belongs to the interval (8, +infinite).
The
common solution of the system is the empty set since there is no value for x to satisfy
both inequalities at the same time.
