Step-by-step explanation:
Given equation is :

The equation can be solved for a as follows :
Step 1.
Cross multiply the given equation

Step 2.
Now subtract b on both sides
3s-b = a+b+c-b
3s-b = a+c
Step 3.
Subtract c on both sides
3s-b-c=a+c-c
⇒ a=3s-b-c
The statement that is true for Darpana is " In step 3, she needed to subtract c rather than divide".
