OpenStudy (anonymous):
is it 13y-1x?
OpenStudy (anonymous):
almost, you just have to be careful with negative signs. Would it help if it was written -13y+(-6x-7x)
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
is it plus instead of minus?
OpenStudy (anonymous):
You mean between the -13y and the -6x? That's just a way to look at it that helps you to combine terms. The terms you combine are (-6x) and (-7x), which together give you a (-13x)
