453-X=199

To solve the equation \( 453 - X = 199 \), you need to isolate \( X \).

1. Subtract 199 from both sides of the equation: \[ 453 - X - 199 = 199 - 199 \] This simplifies to: \[ 453 - 199 - X = 0 \] or: \[ 254 - X = 0 \]

2. Now, add \( X \) to both sides: \[ 254 = X \]

So, the solution is: \[ X = 254 \]
