Explanation:
To simplify the expression "P = c + a + b" for "c", we need to isolate "c" on one side of the equation.
Starting with the given equation:
P = c + a + b
To isolate "c", we can subtract "a" and "b" from both sides of the equation:
P - a - b = c
Therefore, the simplified expression for "c" is:
c = P - a - b
