Let's solve the equation step by step.
Starting with the equation:
\[ 10x + 13 = -12 \]
-
Subtract 13 from both sides: \[ 10x + 13 - 13 = -12 - 13 \] \[ 10x = -25 \]
-
Divide both sides by 10: \[ x = \frac{-25}{10} \] \[ x = -\frac{25}{10} \] \[ x = -\frac{5}{2} \]
Now let's fill in the required parts:
-
After subtracting 13 from both sides, we had:
10x = −25 -
After dividing both sides by 10, we found:
x = −\frac{25}{10} or −\frac{5}{2}
In a single line, the completed solution looks like:
10x + 13 = −12
10x = −25
x = −\frac{25}{10} or x = −\frac{5}{2}.
