To solve the equation \( -10x + 1 + 7x = 37 \), we can first combine the like terms:
\[ -10x + 7x + 1 = 37 \]
This simplifies to:
\[ -3x + 1 = 37 \]
Next, we subtract 1 from both sides:
\[ -3x = 36 \]
Now, divide both sides by -3:
\[ x = \frac{36}{-3} = -12 \]
Thus, the solution is:
\[ x = -12 \]
Therefore, the correct answer is \( x = -12 \).
