Which of the following is equivalent to the pair of inequalities x + 5 > 10 and x - 1 <= 5 ?  Choose the correct choice from the following answers:
A) 2 < x < 16  B) 2 <= x < 4  C) 2 < x <= 8  D) 4 < x <= 8  E) 5 < x <= 6
Solution:   Let’s isolate x in both inequalities, starting with x + 5 &gt; 10.   x + 5 &gt; 10   x &gt; 5   Next we isolate x in the inequality x – 1  5.   x – 1 &lt;= 5   x &lt;= 6   Bringing these two inequalities together we know:   5 &lt; x &lt;= 6   The answer is 5 &lt; x &lt;= 6.
