hey, how's it going?
OpenStudy (anonymous):
hi can you help me out with this equation?
OpenStudy (anonymous):
sure, so by the distributive property, 7m-2m-(-9) = 39
OpenStudy (anonymous):
5m+9=39, subtract 9 from both sides, 5m+9-9=39-9, 5m = 30
OpenStudy (anonymous):
divide both sides by 5, (5m)/5 = 30/5 , m = 6
