Fill in the Blank

An HVAC control systems technician is programming an automated climate control valve. The adjustment value xx (in millimeters) must satisfy two structural safe-operating constraints: 5(3x−1)≤10{}5(3x-1) \leq 10 and 4(x+3)<8{}4(x+3) < 8. After solving the first constraint, the technician gets x≤1x \leq 1. After solving the second constraint, the technician gets x<−1x < -1. To find the overlapping safe zone where both constraints are met, the technician must find the intersection of these two sets. In interval no
