Solve for b P=a+b+c

Problem

P=a+b+c

Solution

1. Identify the variable to isolate, which is b

2. Subtract a from both sides of the equation to move it away from b

P−a=b+c

3. Subtract c from both sides of the equation to isolate b completely.

P−a−c=b

4. Rearrange the equation to place b on the left side.

b=P−a−c

Final Answer

b=P−a−c
