Question

solve the equation $-8 = 3d + 4$. how can you isolate $d$? $-8 = 3d + 4$ \\ - 4 \\ \\ \\ \\ - 4 \\ $-12 = 3d$ subtract 4 on both sides. ? on both sides. options for ? (dropdown): add, subtract, multiply by, divide by

Explanation:

Step1: Analyze the equation after first step

After subtracting 4 from both sides, we have \(-12 = 3d\). To isolate \(d\), we need to get rid of the coefficient 3 that is multiplied with \(d\).

Step2: Determine the operation

The inverse operation of multiplication is division. So we need to divide both sides by 3. So the operation is "Divide by" and the number is 3.

Answer:

Divide by, 3
