$P - 3 a - 3 c = b + 3 a + 3 c - 3 a - 3 c$

Step 1

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

$b + 3 a + 3 c - 3 a - 3 c = P - 3 a - 3 c$

Step 2

Combine the opposite terms in $b + 3 a + 3 c - 3 a - 3 c$ .

Step 2.1

Subtract $3 a$ from $3 a$ .

$b + 3 c + 0 - 3 c = P - 3 a - 3 c$

Step 2.2

Add $b + 3 c$ and $0$ .

$b + 3 c - 3 c = P - 3 a - 3 c$

Step 2.3

Subtract $3 c$ from $3 c$ .

$b + 0 = P - 3 a - 3 c$

Step 2.4

Add $b$ and $0$ .

$b = P - 3 a - 3 c$
