To solve the equation for \( m \), we start with the equation:
\[ -5 = 3m - 14 + 12 \]
First, simplify the right side:
\[ -5 = 3m - 2 \]
Next, add 2 to both sides:
\[ -5 + 2 = 3m \]
\[ -3 = 3m \]
Now, divide both sides by 3:
\[ m = -1 \]
It seems there was a bit of confusion in your question regarding \( x \). If you meant to solve for \( m \) rather than \( x \), then we have \( m = -1 \).
If there is a specific context for \( x \) or if the original equation had \( x \) involved, please clarify!
