***** On the off-chance that the question was asking about the solution set to the joining of the two cases where
           5X < -5    and ALSO    X - 2 < 2
******** then you are looking for the domain where
                x ε ( - ∞ , -1 ) and also X ε ( - ∞ , 4 )
*********** The range of X ε ( - 1 , 4 ) is not valid as it is excluded by the first set so the answer would be
                         X ε ( - ∞ , -1 )
 
Otherwise, Parviz F. was definitely right.

5x < −5 AND x − 2 < 2, so the solution set contains all x-values that satisfy BOTH inequalities; i.e., x ∈ ( - ∞ , -1 ). Tiffany's right.
