Final answer:
To rearrange b - 2x = n to make b the subject, add 2x to both sides of the equation.
Step-by-step explanation:
To make b the subject of the equation b – 2x = n, we need to isolate b on one side of the equation. Here are the steps:
- Start with the equation b – 2x = n.
- Add 2x to both sides of the equation to get b alone.
- The equation becomes b = 2x + n.
So, the rearranged equation with b as the subject is b = 2x + n.
