d-2=1

To solve the equation \(d - 2 = 1\), you can isolate \(d\) by adding 2 to both sides of the equation. Here’s how it works step-by-step:

1. Start with the equation: \[ d - 2 = 1 \]

2. Add 2 to both sides: \[ d - 2 + 2 = 1 + 2 \]

3. Simplifying both sides gives: \[ d = 3 \]

So the solution is \(d = 3\).
