... • Example: The sum of the measures of angles X and Y is 180 (They are supplementary). The measure of angle X is 24 greater than angle Y. • Equation one. “The sum of X & Y is 180”: x + y = 180 • Equation two. “Angle X is 24 greater than y”: x = 24 + y • Since we have x equal to something, we can subs ...
