Question

1. 4 = 5d - 16

Explanation:

Step1: Add 16 to both sides

To isolate the term with \(d\), we add 16 to both sides of the equation \(4 = 5d - 16\). This gives us \(4 + 16 = 5d - 16 + 16\). Simplifying both sides, we have \(20 = 5d\).

Step2: Divide both sides by 5

Now, to solve for \(d\), we divide both sides of the equation \(20 = 5d\) by 5. So, \(\frac{20}{5}=\frac{5d}{5}\), which simplifies to \(4 = d\) or \(d = 4\).

Answer:

\(d = 4\)
