    Basic word problem, finding x and y

    Hey Guys,

    Here is a simple word problem. I found some set up online but it does not use both variables x and y. Instead, it uses the variable x only.
    Here is the question:

    Two angles are supplementary. One angle is 24 morethan twice the other. Using two variables
    x and y, find themeasure of each angle.

    Here is the answer online:
    x + 2x - 24 = 180
    3x = 156 x = 52 degrees, one angle, other one is 128.

    How would you set this up by using 2 variables?

    one way would be

    x + y = 180$ because the angles are supplementary$

    y=2x+24$ by the 2nd statement of the problem$

    Now just plug the 2nd equation into the first to obtain

    x+(2x+24)=180

    3x + 24 = 180

    3x=156

    x=52

    y=2(52)+24=104+24=128
