I was given a problem in my math textbook, which is for my Algebra 2 class. It is in the section for "Rewriting Equations" and it says:
"Solve the formula: t = a + n (n - 1 )d for n"
I was looking through the examples, and maybe it is just not me understanding but I just can't understand what to do here. Thanks in advance for anyone who can help me out.
