Question

Given p = 3k + 8, express k in terms of p.

Answer 1

k = (p -8)/3

Explanation:

To solve for k, we undo what is done to it.

p = 3k +8 . . . . . given

p -8 = 3k . . . . . . subtract the added constant

(p -8)/3 = k . . . . . divide by the multiplier

The desired expression is ...

k = (p -8)/3
