Answer:
a=-1
Step-by-step explanation:
To make the solution easier let's equate to zero
-2/3a+5/6a-1/6=0
Add 1/6 to both sides
-2/3a+5/6a=1/6
Look for LCM for those ones on the left side... the LCM is 6
-6a+5a/6=1/6
-a/6=1/6
Cross multiply
-6a=6
Divide both sides by -6
a=-1
Therefore the final answer is -1
One has to be much more careful while solving this question...so else if you miss any steps... your final answer will be wrong...my advice is that you should always be calm whenever you see any mathematics question and reason well to it as well
