Solve the following equation: -6(1.5x + 3) - 123 = - (13 - 7x)

Let's solve this equation step-by-step!

Step-by-step solution:

1. Step 1: Distribute the -6 on the left side and the negative sign on the right side.
   \( -6 \cdot 1.5x - 6 \cdot 3 - 123 = -13 + 7x \)
   \( -9x - 18 - 123 = -13 + 7x \)
2. Step 2: Combine the constant terms on the left side.
   \( -9x - 141 = -13 + 7x \)
3. Step 3: Move all terms with x to one side and constant terms to the other. Let's add 9x to both sides and add 13 to both sides.
   \( -141 + 13 = 7x + 9x \)
   \( -128 = 16x \)
4. Step 4: Isolate x by dividing both sides by 16.
   \( x = \frac{-128}{16} \)
   \( x = -8 \)

Answer: -8
