To solve the equation \(10x + 13 = -12\), let's complete the solution step by step:
-
Start with the original equation: \[ 10x + 13 = -12 \]
-
Subtract 13 from both sides: \[ 10x = -12 - 13 \] \[ 10x = -25 \]
-
Divide both sides by 10: \[ x = \frac{-25}{10} \]
-
Simplifying the fraction, we find: \[ x = \frac{-5}{2} \]
So, the solution can be filled in as:
- For \(10x =\): -25
- For \(x =\): \(-\frac{5}{2}\)
