Question

solve the equation -8 = 3d + 4. what is the value of 3d? -8 = 3d + 4 - 4 - 4 ← subtract 4 on both sides. □ = 3d

Explanation:

Step1: Subtract 4 from -8

We start with the equation \(-8 = 3d + 4\). When we subtract 4 from both sides, we calculate \(-8 - 4\).
\(-8 - 4 = -12\)

Step2: Result for 3d

After subtracting 4 from both sides, the left - hand side becomes \(-12\) and the right - hand side becomes \(3d\) (since \(3d + 4-4=3d\)). So, \(3d=-12\).

Answer:

\(-12\)
