If `8-5x = -47`, then 2x = ?

Options

A. 7.8
B. 15.6
C. 11
D. 22

Answer

To solve the equation \( 8 - 5x = -47 \) and find the value of \( 2x \), we can follow these steps:

### Step 1: Isolate the term with \( x \)
We start with the equation:
\[ 8 - 5x = -47 \]
To isolate the term with \( x \), we can subtract 8 from both sides:
\[ -5x = -47 - 8 \]

### Step 2: Simplify the right side
Now, we simplify the right side:
\[ -5x = -55 \]

### Step 3: Solve for \( x \)
Next, we divide both sides by -5 to solve for \( x \):
\[ x = \frac{-55}{-5} \]
This simplifies to:
\[ x = 11 \]

### Step 4: Find \( 2x \)
Now that we have \( x \), we can find \( 2x \):
\[ 2x = 2 \times 11 = 22 \]

### Final Answer
Thus, the value of \( 2x \) is:
\[ \boxed{22} \]
