To find the undefined value in the equation \( 14 = 7 \cdot 9 + 4x \), we first simplify the equation.
Start by calculating \( 7 \cdot 9 \): \[ 7 \cdot 9 = 63 \] So the equation becomes: \[ 14 = 63 + 4x \]
Next, we want to isolate \( 4x \). Subtract \( 63 \) from both sides: \[ 14 - 63 = 4x \] \[ -49 = 4x \]
Now, divide by \( 4 \) to solve for \( x \): \[ x = \frac{-49}{4} \]
The only potential undefined value arises when the variable appears in a way that could lead to division by zero. In this case, \( x \) can take any real value, but if we consider definitions that make a typical operation invalid, the focus would be on the context provided.
The choices provided include:
- \( x \neq 0 \)
- \( x \neq \frac{9}{4} \)
- \( x \neq -\frac{49}{4} \)
- \( x \neq -94 \)
The value we found for \( x \) is \( -\frac{49}{4} \), but none of the options explicitly require that \( x \) can't be any one number alone.
Since it appears that the query about undefined values might refer to when such a problem typically fails, we would concentrate on that specific outcome.
In conclusion, based on the equation given, \( x \) cannot equal \(-\frac{49}{4}\) as that's the value of \( x \). However, option 3 matches that requirement:
x≠−94 is not directly relating to \( x = -\frac{49}{4} \).
Hence, based on the value computed, and the option closest to the computed result, the response that could be deemed relevant is:
x ≠ -49.
