Darpana solved the equation s = StartFraction a + b + c Over 3 EndFraction for a. Her steps are shown below: 1. Multiply by 3: s

Harman [31]

Answer:

Option (c) is correct.

Step-by-step explanation:

Given equation is :

$s=\dfrac{a+b+c}{3}$

The equation can be solved for a as follows :

Step 1.

Cross multiply the given equation

$3s=a+b+c$

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".
