Answer:


\boxed{\textsf{The value of x is \textbf{7}.}}

Explanation:

Given that 9213x5 is a multiple of 9 and we need to find out the value of x .So the rule for divisibility for 9 is :-

Test for Divisibility by 9 :-

A number is divisible by 9 if the sum of the digits is divisible by 9 .

Here the sum of the digits is :-


\sf\implies Sum_((digits))= 9+2+1+3+x+5=\pink{20+x}

Now here to make 20 +x divisible by 9 is should be equal to 27 since 27 is the nearest smallest multiple of 9 .


\sf\implies 20 + x = 27 \\\\\sf\implies x = 27-20 \\\\\sf\implies\boxed{\pink{\sf x = 7 }}
