# Question: x in terms of y

## Comment on x in terms of y

### (180 - y) + x + 22 = 180

(180 - y) + x + 22 = 180
-y + x + 22 = 0
x = y - 22

Perfect!

### That's exactly what i did! On

That's exactly what i did! On an exam where you're trying to save time, why introduce another variable? I get it for learning purposes, but doesn't it complicate matters without benefit in practice?

x = 180 - (180 - y) - 22 also works and is the quickest possible method I see. 1 step.

### As is the case with most GMAT

As is the case with most GRE math questions, there are several possible approaches. Yours is also a perfectly valid solution, and it's faster than the two solutions in the video.

That said, the solutions in the video (especially the 2nd solution) aren't really that time consuming.

### I loved your Geometry Module

I loved your Geometry Module slideshow.
Thanks

Thanks Anil!

### I like you showed the 43+x

I like you showed the 43+x approach. I don't know if I would have considered treating that as a single angle. It's a good method to know.
