When you simplify the expression \( 5d - 4d \), you combine like terms. Since both terms involve the variable \( d \), you subtract the coefficients: \( 5 - 4 = 1 \). Therefore, the simplified expression is \( 1d \) or simply \( d \). For a quick check, think about it this way: If you had five apples and then gave away four, you’d be left with just one apple. Similarly, you’re left with one \( d \) when you subtract!
