9+x=12 Can you guys please tell me the answer

3

Step-by-step explanation:

Let's go through this together.

Step 1) Rearrange Terms (Optional)

9 + x = 12

x + 9 =12

Step 2) Subtract 9 from both sides of the equation

x + 9 = 12

   -9    -9

Step 3) Simplify

If we subtract 9 on both sides, we end up with:

x + 0 = 3

Since 0 no longer has any part in the equation, we can conclude that:

x = 3

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
