You are told 2/9 = 16
Let total number of batteries = x
So you now have 2/9x = 16
To find x divide both sides by 2/9
X = 72 total batteries
Either BOD or AOD
Hope this helps c:
Multiply both sides by 6
(b-4)/6*6= b-4
b/2*6= 3b
Rewrite the equation
b-4= 3b
Subtract b from both sides
-4=2b
Divide both sides by 2
-2=b
Final answer: b=-2
