I did, but after 22 years I forgot how to solve algebra without being given at least 1 of the variables. 🥺

But also I still dont know how I would prove it's a line even if I got the x+y=w+z part. I could say 1+2=1+2. So 3. How is 3 a line? I have no idea. 3 is a number not a line. 😩

Unless... 3 is a squiggly line? 🤔

Edit: Bit disappointed nobody came to shit all over my math skills. Especially since halfway through typing the comment, I forgot the second half of the problem. 🤣

    You do have a number, it's just not written down! It's that a full circle is 360 degrees

    • Let x + y = d and w + z = e for easier writing
    • We know d + e = 360 degrees (a full circle)
    • d = e, so 2d = 360, so d = 180 degrees
    • The angle AOB = d, and d = 180 degrees, so AB is a straight line

    The actual maths is really easy, the bit that I assume is tripping you up is the realisation that you have more information than the words of the question
