plese urgent ​

Answer 1

Answer:

x = 4

Step-by-step explanation:

A number is divisible by 11 if the difference of the sum of the numbers in even positions and the sum of the numbers in the odd positions is 11

In 67x19 the digits in odd positions are 6 , x , 9

Sum = 6 + x + 9 = 15 + x

In 67x19 the digits in even positions are 7 , 1

Sum = 7 + 1 = 8

15 + x - 8 = 11

7 + x = 11

x = 11 - 7

x = 4
