In 5_,278, the difference between the values of the digits in the thousands and the tens is 8,930. What is the digit in the thousands

Answer-
The digit in the thousand place is '9'.
Solution-
The given number is 5_278.
The difference between the values of the digits in the thousandth place and the tenth place is 8930.
The digits in the tenth place is already given, which is 7
Let's assume the digits in the thousandth place is x,
So the value of the thousand's becomes [tex](x \times 1000) = 1000x[/tex]
and the value of the ten's is 7 × 10 = 70
Writing an equation for this,
[tex]1000x - 70 = 8930 \Rightarrow 1000x=9000 \Rightarrow x=9[/tex]
