Question

If ey/n + k = t, what is y in terms of e, n, k, and t?

1) y= tn+k/e

2) y= tn-k/e

3) y= n(t+k)/e

4) y= n(t-k)/e​

Answer 1

option 4

Explanation:

To write in terms of y

Step 1: subtract k from both sides

`\sf (ey)/(n) + k - k = t -k\\\\\\(ey)/(n)=t-k`

Step 2: Multiply the entire equation by n

`\sf n*(ey)/(n)=n*(t-k)\\\\\\ey=n(t-k)`

Step 3: Divide the entire equation by 'e'

`\sf (ey)/(e)=(n(t-k))/(e)\\\\\\\boxed{y =(n(t-k))/(e)}`
