Final answer:

To make y the subject of the formula x = a - 2b, add 2b to both sides, subtract x from both sides, and divide by 2.

Step-by-step explanation:

To make y the subject of the formula x = a - 2b, we need to isolate y on one side of the equation. Here are the steps:

  1. Start with the equation x = a - 2b.
  2. Add 2b to both sides of the equation to get x + 2b = a.
  3. Subtract x from both sides of the equation to get 2b = a - x.
  4. Finally, divide both sides of the equation by 2 to solve for b: b = (a - x) / 2.
