If r equals 5z then 15z equals 3y then r equals what?
Don't do the question immediately, read the sentence 3 times and
visualize what is it saying. Its just like hitting you from the
left to right brain and back to left brain again, but focus
thinking on the right, its just confusing as it sounds but its just
simplicity in a rather complex sentence if you did not read it
carefully.
Since R = 5Z
then 15Z = 3Y
then R = ?
Since it means one R = 5Z
15Z = 3y, saying 3times the Y = 15Z
So you want to find out R =?, 5Z = R, 10Z = 2Y so R = Y!
