Answer:
the answer is C
Step-by-step explanation:
You have to distribute 1st and multiply both sides in order to correvtly get an accurate equation to find X.
Answer:
n
b = ---------
(g+l)
Step-by-step explanation:
We need to isolate b. Starting from (g+l)b=n, we divide both sides by (g+l), obtaining
n
b = ---------
(g+l)
