Answer:

x = -2

Step-by-step explanation:

Step 1: Write equation

4(5x + 7) = -45 + 33

Step 2: Solve for x

  1. Distribute 4: 20x + 28 = -45 + 33
  2. Combine like terms: 20x + 28 = -12
  3. Subtract 28 on both sides: 20x = -40
  4. Divide both sides 20: x = -2

Step 3: Check

Plug in x to verify it's a solution.

4(5(-2) + 7) = -45 + 33

4(-10 + 7) = -12

4(-3) = -12

-12 = -12
