Answer:
The solution is the interval (3,7)
Explanation:
we have the compound inequality
![3<x<7](https://img.qammunity.org/2021/formulas/mathematics/middle-school/szux00m0u66y5enr1d3upqo2r1o7a6077o.png)
This is the same that the system of inequalities
x> 3 and x<7
Solve the system of inequalities
x>3
The solution is the interval (3,∞)
X<7
The solution is the interval (-∞,7)
therefore
The solution is
(3,∞) ∩ (-∞,7)=(3,7)
