Solve for the given letter.
-4k + ar = r - 9y for r

Question

Quizplus · Accepted Answer

First, we can simplify the equation by moving all the terms with r to one side:
4k + ar - r = -9y
Then, we can factor out r from the left side:
r(1-a) = -9y - 4k
Finally, we can solve for r by dividing both sides by (1-a):
r = (-9y - 4k) / (1-a)
Therefore, the answer is B. Starting with the given equation:

4k + ar = r - 9y

We want to isolate r on one side of the equation, so we'll move all the terms containing r to one side and factor out r:

4k + ar - r = -9y

r(a - 1) = -9y - 4k

r = (-9y - 4k) / (a - 1)

So the correct answer is (B).
