Let's solve the equation step by step and fill in the blanks.
The given equation is:
\[ 10x + 13 = -12 \]
- Subtract 13 from both sides:
\[ 10x = -12 - 13 \] \[ 10x = -25 \]
- Divide both sides by 10:
\[ x = \frac{-25}{10} \] \[ x = -2.5 \]
Now, let's fill in the answer in the format provided:
- \( 10x = -25 \) (after subtracting 13 from both sides)
- \( x = -2.5 \) (after dividing both sides by 10)
So the completed solution is:
\[ 10x + 13 = -12 \]
\[ 10x = -25 \]
\[ x = -2.5 \]
