The correct Answer is:
To solve the equation \( 98 + 743 + 198 = 800 - x \), we will follow these steps: ### Step 1: Calculate the sum of the left side First, we need to add the numbers on the left side of the equation: \[ 98 + 743 + 198 \] **Calculation:** - Start with \( 98 + 743 \): \[ 98 + 743 = 841 \] - Now add \( 198 \): \[ 841 + 198 = 1039 \] So, \( 98 + 743 + 198 = 1039 \). ### Step 2: Set up the equation Now we can rewrite the equation using the sum we just calculated: \[ 1039 = 800 - x \] ### Step 3: Isolate \( x \) To find \( x \), we need to isolate it on one side of the equation. We can do this by rearranging the equation: \[ x = 800 - 1039 \] ### Step 4: Perform the subtraction Now, perform the subtraction: \[ 800 - 1039 = -239 \] ### Step 5: Conclusion Thus, we find that: \[ x = -239 \] ### Final Answer The value of \( x \) is \( -239 \). ---
