    Basic word problem I can't set up.

    Two angles are supplementary. One angle is 24 degrees more than twice the other. Using two variables x and y, find the measure of each angle.




    Okay, so supplementary = 180 degrees.

    x + y = 180 degrees.

    One angle is 24 degrees more than twice the other. (I don't quite understand this part)

    x+24 + 2y = 180?





    angles come up to be 128 and 52 degrees. I don't think I am structuring it properly.

    Re: Basic word problem I can't set up.

    Okay, so I believe I have the answer.

    x + y = 180 degrees

    x + 24 + 2y = 180

    //isolate one variable

    x = -24 + 2y + 180 // I moved everything to the right side of x


    // I substitute -24 + 2y + 180 for x

    (-24 + 2y + y) + 180 = 0 // Wouldn't it be -24 + 2y + y + 180 = 180. Though it wouldn't give me the correct answer.

    //combine like terms

    3y + 156 = 0

    3y / 3 = -156 / 3

    y = -52 // I don't know why I got a negative. I might need help getting this clarified.


    //So I just plug 52 back into y

    x + 52 = 180
    x = 128

    Re: Basic word problem I can't set up.

    Here we have: x + y = 180 -------- (1) Also we have
    X = 2y + 24 ----- (2)
    Plugging in for x from (2) in (1) we get
    2y + 24 + y = 180 that is 3y = 154 and y = 52 that will give x = 128
