The equation you're showing seems incorrect as written. When you add 454 to something, it does not equal 892.
To find out what number \( x \) should be added to 454 to equal 892, you can set up the equation:
\[ 454 + x = 892 \]
To solve for \( x \), subtract 454 from both sides:
\[ x = 892 - 454 \] \[ x = 438 \]
So, \( 454 + 438 = 892 \).
