Solve for a P=a+3b+4c

$P = a + 3 b + 4 c$

Step 1

Rewrite the equation as $a + 3 b + 4 c = P$ .

$a + 3 b + 4 c = P$

Step 2

Move all terms not containing $a$ to the right side of the equation.

Subtract $3 b$ from both sides of the equation.

$a + 4 c = P - 3 b$

Subtract $4 c$ from both sides of the equation.

$a = P - 3 b - 4 c$
