Azarel spent half of his weekly allowance on comic books. To earn more money his parents let him clean the windows in the house for $9. What is
hsi weekly allowance if he ended up with $12? *

His weekly allowance is $6.

Step-by-step explanation:

You can get the answer by using algebraic expressions.

Let 2x be Azarel's weekly allowance.

Let (2x) be the amount after Azarel spends his allowance on comic books.

The equation will be: 12=2x+9-(2x)

Let's solve for x:

Step 1: 12=2x+9-x

Step 2: 12=x-9

Step 3: x=12-9

Step 4: x=3

Step 5: Replace 2x with 2(3) = 6

The answer is $6. This is the allowance of Azarel every week. He spends $3 for comic books weekly, which is half of $6.
