Answer:
76 seconds
Step-by-step explanation:
You need to find the first common multiple of both 7 and 8.  the LCM  is actually the numbers multiplies by each other, or 56. 
 
        
             
        
        
        
First we have - 6 < - 7 - 4x 
Then we need to isolate the x of the inequality 4x < - 7 + 6
 4x < - 1
 x < - 1/4 
The values less than - 1/4 are solutions for x
