To solve the equation 2a - 2 = 20, we need to isolate the variable 'a' on one side of the equation. Let's go through the steps one by one:

Step 1: Simplify both sides of the equation
2a - 2 = 20

We can start by adding 2 to both sides of the equation to eliminate the -2 on the left side:
2a - 2 + 2 = 20 + 2
2a = 22

Step 2: Divide both sides of the equation by 2
To isolate 'a', we divide both sides of the equation by 2:
2a/2 = 22/2
a = 11

Therefore, the value of 'a' that satisfies the equation 2a - 2 = 20 is 11. Hence, option 'C' is the correct answer.

Let's summarize the steps:

Step 1: Simplify both sides of the equation
2a - 2 = 20

Step 2: Add 2 to both sides of the equation
2a - 2 + 2 = 20 + 2
2a = 22

Step 3: Divide both sides of the equation by 2
2a/2 = 22/2
a = 11

Therefore, the value of 'a' is 11, which matches option 'C'.
