1 answer

To solve the equation \( 3(x-5) + 2x = 0 \), let's go through it step by step. We'll fill in each part of the process:

  1. Distribute the \(3\):
    \(3(x-5) = 3x - 15\)
    Therefore, the equation becomes:
    Step 1: \(3x - 15 + 2x = 0\)

  2. Combine like terms:
    \(3x + 2x = 5x\)
    So, the equation simplifies to:
    Step 2: \(5x - 15 = 0\)

  3. Add 15 to both sides:
    \(5x = 15\)
    Step 3: \(5x = 15\)

  4. Divide by 5:
    \[x = \frac{15}{5} = 3\]
    Step 4: \(x = 3\)

So, the completed steps are:

  1. \(3x - 15 + 2x = 0\)
  2. \(5x - 15 = 0\)
  3. \(5x = 15\)
  4. \(x = 3\)
