Question

solve for d.
3d - 8 = 7
d = ?

Explanation:

Step1: Add 8 to both sides

To isolate the term with \( d \), we add 8 to both sides of the equation \( 3d - 8 = 7 \). This gives us \( 3d - 8 + 8 = 7 + 8 \), which simplifies to \( 3d = 15 \).

Step2: Divide by 3

Now, to solve for \( d \), we divide both sides of the equation \( 3d = 15 \) by 3. So, \( \frac{3d}{3} = \frac{15}{3} \), which simplifies to \( d = 5 \).

Answer:

\( d = 5 \)
