The intersection of
is 
Explanation:
The expression is 
To determine the intersection of these two inequalities, let us solve the two inequalities separately.
Consider 
Subtracting both sides by 1, we have,
Also, consider 
Adding both sides by 4, we have,

Using these two simplified inequalities in the expression, we have,

Writing this in the interval notation, we get,

Hence, the intersection of the two interval is

Thus, the intersection of
is
