Is there more to this question or no?
8/x-7=7/2
16=7(x-7) cross multiply
16=7x-49
-7x=-49-16
-7x=-65 divides each side by -7
-7x/7=-65/7
X=65/7
Alternative form
X=92/7
Which is 1st options in your questions.

Let c represent the cost and r represent the number of rooms, then
a.) c = 22r
b.) 200 = 22r
r = 200/22 = 9.09 ≈ 9 rooms
c.) 200 - 40 = 22r
r = 160/22 = 7.27 ≈ 7 rooms
