The equation 10x +13= -12

10x = ____ subtract 13 from both sides
X=___ divide both sides by 10

1 answer

Let's solve the equation step by step.

  1. Start with the original equation: \[ 10x + 13 = -12 \]

  2. Subtract 13 from both sides: \[ 10x = -12 - 13 \] \[ 10x = -25 \]

  3. Now, divide both sides by 10: \[ x = \frac{-25}{10} \] \[ x = -2.5 \]

So, filling in the blanks from your prompt:

  1. \( 10x = -25 \) (after subtracting 13 from both sides)
  2. \( x = -2.5 \) (after dividing both sides by 10)
