Final answer:
To solve for b in the equation d = 3a + 3b, isolate b on one side by subtracting 3a from both sides and dividing by 3.
Step-by-step explanation:
To solve for b in the equation d = 3a + 3b, we need to isolate b on one side of the equation. Here's how:
- Start with the equation d = 3a + 3b.
- Subtract 3a from both sides of the equation, which gives you d - 3a = 3b.
- Divide both sides of the equation by 3, which gives you (d - 3a) / 3 = b.
Therefore, b = (d - 3a) / 3. This is the solution for b in terms of d and a.
