If ey/n + k = t, what is y in terms of e, n, k, and t? (a good explanation would be appreciated)

So your goal is to set it equal to Y, so you have to start by subtracting k and you get t-k, then you have to get rid of the fraction by multiplying both sides by the denominator (n), so then you get n(t-k) and the only thing left is to divide by the e, and you get 4

Idon’t exactly understand but i think dbc=rst
