(X-536)-143=724

To solve the equation \( (X - 536) - 143 = 724 \), follow these steps:

1. Start by simplifying the left side: \[ X - 536 - 143 = 724 \]

2. Combine the constants on the left side: \[ X - 679 = 724 \]

3. Now, isolate \( X \) by adding 679 to both sides: \[ X = 724 + 679 \]

4. Perform the addition: \[ X = 1403 \]

So, the solution is: \[ X = 1403 \]
