solve the formula for the specified variable.
p = s1 + s2 + s3 for s3
a s3 = s1 + p - s2
b s3 = p - s1 - s2
c s3 = p + s1 + s2
d s3 = s1 + s2 - p

Explanation:

Step1: Isolate $s_3$

Subtract $s_1$ and $s_2$ from both sides of the equation $P = s_1 + s_2 + s_3$.
$P-(s_1 + s_2)=s_1 + s_2 + s_3-(s_1 + s_2)$

Step2: Simplify the equation

$P - s_1 - s_2=s_3$

Answer:

B. $s_3 = P - s_1 - s_2$
