Not sure what x is tho

OpenStudy (mathsucks321):

Or would I add it to get x=-5

OpenStudy (seratul):

You made a mistake with your equation. It should be x+105+x+85=180

OpenStudy (mathsucks321):

Okay so it is -5 ty

OpenStudy (seratul):

No problem.

OpenStudy (3mar):

It is a linear pair, their sum is add up 180 like what @Seratul said!
