Simplify the expression:
8(2x - 3) - 6x = 8×2x - 8×3 - 6x = 16x - 24 - 6x = 10x - 24
for x=3
put value of "x" to the expression:
<u>10×3 - 24 = 30 - 24 = 6</u>

Step-by-step explanation:
(A n b) = this means that we need d value that is in a and b only
ans= (1,2,4)
 
        
             
        
        
        
<span>6 km × 1 hour/(b-4 km) = 12 km × (1 hour/(b+4 km) 
6/(b-4) hours = 12/(b+4) hours
6(b+4) = 12(b-4)
6b + 24 = 12b - 48
72 = 6b
b = 12
