Solve for a p=a+b+c

Problem

p=a+b+c

Solution

1. Identify the variable to isolate, which is a

2. Subtract b from both sides of the equation to begin isolating a

p−b=a+c

3. Subtract c from both sides of the equation to finish isolating a

p−b−c=a

4. Rearrange the equation so that a is on the left side.

a=p−b−c

Final Answer

a=p−b−c
