Question

which equation is equivalent to $s = ph + 2b$ when solved for $b$?
a $b = \frac{2s}{ph}$
b $b = \frac{s - ph}{2}$
c $b = \frac{sph}{2}$
d $b = \frac{s - 2}{ph}$

Explanation:

Step1: Isolate the term with $B$

Subtract $Ph$ from both sides:
$S - Ph = 2B$

Step2: Solve for $B$

Divide both sides by 2:
$B = \frac{S - Ph}{2}$

Answer:

B. $B = \frac{S - Ph}{2}$
