Question

solve the equation -8 = 3d + 4. what is the value of d? -8 = 3d + 4 - 4 - 4 ← subtract 4 on both sides. -12 = 3d (-12)/3 = (3d)/3 ← divide by 3 on both sides.? = d

Explanation:

Step1: Simplify the equation

We start with the equation \(-8 = 3d + 4\). To isolate the term with \(d\), we subtract 4 from both sides.
\[
-8 - 4=3d + 4- 4
\]
Simplifying both sides, we get \(-12 = 3d\).

Step2: Solve for \(d\)

Now, to solve for \(d\), we divide both sides of the equation \(-12 = 3d\) by 3.
\[
\frac{-12}{3}=\frac{3d}{3}
\]
Simplifying both sides, we find that \(d=- 4\).

Answer:

\(-4\)
