Answer:

x = 1

Explanation:

Step 1: Write equation

-5(2x - 5) - 3x - 5 = 7

Step 2: Solve for x

  1. Distribute -5: -10x + 25 - 3x - 5 = 7
  2. Combine like terms: -13x + 20 = 7
  3. Subtract 20 on both sides: -13x = -13
  4. Divide both sides by -13: x = 1

Step 3: Check

Plug in x to verify it's a solution.

-5(2(1) - 5) - 3(1) - 5 = 7

-5(2 - 5) - 3 - 5 = 7

-5(-3) - 8 = 7

15 - 8 = 7

7 = 7
