Options

A. 11080
B. 10190
C. 11075
D. 11085

Answer

To solve the equation \( (? - 968) \div 79 \times 4 = 512 \), we will follow these steps:

### Step 1: Rewrite the equation
Let \( x \) represent the question mark. The equation can be rewritten as:
\[ (x - 968) \div 79 \times 4 = 512 \]

### Step 2: Isolate the division
To isolate the division, we can first multiply both sides of the equation by \( 79 \):
\[ (x - 968) \times 4 = 512 \times 79 \]

### Step 3: Calculate \( 512 \times 79 \)
Now, we need to calculate \( 512 \times 79 \):
\[ 512 \times 79 = 40448 \]
So, the equation now looks like:
\[ (x - 968) \times 4 = 40448 \]

### Step 4: Divide both sides by 4
Next, we divide both sides of the equation by \( 4 \):
\[ x - 968 = \frac{40448}{4} \]

### Step 5: Calculate \( \frac{40448}{4} \)
Now, we calculate \( \frac{40448}{4} \):
\[ \frac{40448}{4} = 10112 \]
So now we have:
\[ x - 968 = 10112 \]

### Step 6: Solve for \( x \)
Finally, we add \( 968 \) to both sides to solve for \( x \):
\[ x = 10112 + 968 \]

### Step 7: Calculate \( 10112 + 968 \)
Now, we calculate \( 10112 + 968 \):
\[ 10112 + 968 = 11080 \]

### Final Answer
Thus, the value of \( x \) (or the question mark) is:
\[ \boxed{11080} \]
