How do you solve #L = a + (n - L)d# for d?

Answer 1

Eva Adamson

#d=(L-a)/(n-L)#

Subtract #a# from both sides.

#L-a=(n-L)d#

Divide both sides by #(n-L)#

#(L-a)/(n-L)=d#

Rewrite

#d=(L-a)/(n-L)#

To solve the equation L = a + (n - L)d for d, you rearrange the equation to isolate d:

d = (L - a) / (n - L)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
