the measure of one angle is described as twelve more than four times a number. its supplement is twice as large. find the measure of each angle.

if the angle is x, its supplement is 180-x, so just solve

180-x = 2x

x=60

What's all this nonsense about x=4n+12?

If you need to find "the number" then just solve that for n, given that x=60.
