Distribute to get -6x+18+5x=-10
OpenStudy (anonymous):

OpenStudy (nikato):
Add like terms -x+18=-10

Subtract 18 from both sides And finally multiply both sides by -1

Ok subtract 18 from both sides -x+18=-10 -18. -18 --------------- -x=-28 Multiply both sides by -1 x=28
OpenStudy (anonymous):

OpenStudy (nikato):
Combine like terms -6x+5x=-x It's the same thing without the x. -6+5=-1
