Answer:
The check digit is 7.
Step-by-step explanation:
Check digit can be calculated by the following way:
- Add all the digits except the check digit that is the last digit on the right side.
Total = 0 + 2 + 4 + 6 + 7 + 9 + 3 + 6 + 1 + 6 + 3
Total = 47
- Add the digits at odd starting from left, double this amount and finally add it with the total from step 1.
= 0 + 4 + 7 + 3 + 1 + 3
Sum = 18
Doubling the sum = 36
Adding it with the total from step 1, we get
Total = 36 + 47
Total = 83
- Subtract the last digit of the total from step 2 with 10, and this will be check digit.
Check Digit = 10 - 3
Check Digit = 7
Answer:
x = 1
Step-by-step explanation:
7x + 16 = 8x + 15
<u>Step 1</u> : Subtract 15 on both sides
7x + 16 - 15 = 8x
7x + 1 = 8x
<u>Step 2</u> : Subtract 7x on both sides
1 = 8x - 7x
1 = 1x
x = 1
