Question

solve the formula for the indicated variable.
p = a + b + 2c, for a

a =
(use integers or fractions for any numbers in the expression. simplify your answer.)

Explanation:

Step1: Isolate 'a' by subtracting terms

To solve for \( a \) in the formula \( P = a + b + 2c \), we need to isolate \( a \). Subtract \( b \) and \( 2c \) from both sides of the equation.
\[
P - b - 2c = a + b + 2c - b - 2c
\]

Step2: Simplify the right side

Simplifying the right side, the \( b \) and \( -b \) cancel out, and the \( 2c \) and \( -2c \) cancel out, leaving just \( a \) on the right.
\[
a = P - b - 2c
\]

Answer:

\( P - b - 2c \)
