Solve $c = a + ( n - 8 ) d$ for n.
A) $n = c - a + 8$
B) $n = \frac { c - a + 8 d } { d }$
C) $n = \frac { c - a - 8 d } { d }$
D) $n = \frac { c } { d } - a + 8$

Quizplus · Accepted Answer

To solve for n, we want to isolate it on one side of the equation. We can start by subtracting a from both sides:
$$c-a = (n-8)d$$
Next, we can divide both sides by d:
$$\frac{c-a}{d} = n-8$$
And finally, adding 8 to both sides, we get the solution for n:
$$n = \frac{c-a+8d}{d}$$
Thus, the best choice is B.

Solve c=a+(n−8)dc = a + ( n - 8 ) dc=a+(n−8)d

Solve $c = a + ( n - 8 ) d$
