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.
writing and linear equations -
if the angle is x, its supplement is 180-x, so just solve
180-x = 2x
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.
