Answer 1

To find the value that makes the equation undefined, we need to identify when the denominator equals zero.

The equation you've provided can be interpreted as:

\[
\frac{x + 3}{2x + 4} = 18
\]

The denominator is \(2x + 4\). To find when the fraction is undefined, we set the denominator equal to zero and solve for \(x\):

\[
2x + 4 = 0
\]

Subtract 4 from both sides:

\[
2x = -4
\]

Now, divide both sides by 2:

\[
x = -2
\]

Thus, the value that makes the equation undefined is \(\boxed{-2}\).
