Answer:
step 2; a negative times a negative = a positive.
Step-by-step explanation:
-4(6-b)=4
<u>-24 </u><u>+</u><u>4b=4</u>
4b=28
b=7
 
        
             
        
        
        
Let the number of 250g=0.25  kg jars be x and that of 500g=0.5 kg jams be y;
therefore:
total number of jars ws
x+y=511 
x=511-y..........i
total mount kgs was:
0.25x+0.5y=186.5....ii
substituting i in ii
0.25(511-y)+0.5y=186.5
127.75-0.25y+0.5y=186.5
solving for y we get:
0.25y=186.5-127.75
0.25y=58.75
y=58.75/0.25
y=235 jars
and 
x=511-x
=511-235
=276
hence we conclude that there was 235 jars with 0.5 kg almond and 276 jars with 0.25 kg almonds
