To solve the equation \( 14 = 7 \cdot 9 + 4 \cdot x \), let's simplify the terms and isolate \( x \).
First, calculate \( 7 \cdot 9 \):
\[ 7 \cdot 9 = 63 \]
Now, substitute this back into the equation:
\[ 14 = 63 + 4x \]
Next, isolate the term with \( x \) by subtracting 63 from both sides:
\[ 14 - 63 = 4x \]
\[ -49 = 4x \]
Now, divide by 4 to solve for \( x \):
\[ x = \frac{-49}{4} \]
Therefore, the value for \( x \) that is undefined is:
\[ x \neq -\frac{49}{4} \]
In terms of how this answer is presented in the options you provided, it could likely be expressed as:
x ≠ -49
- x does not equal Start Fraction negative 4 over 9 End Fraction
But focusing on your specific question regarding undefined values, the relevant incorrect option must be confirmed from other provided responses.
Thus, the undefined value must be approached carefully; however, in essence, the answer pointing to:
x does not equal Start Fraction negative 49 over 4 End Fraction.
is the correct interpretation of the results. Re-examine the options for absolute alignment in formatting and context applied.
