Best ResponseYou've already chosen the best response.1the 6b means "6 times b" we need to undo the multiplication so we divide both sides by 6 to isolate b dw:1438647301431:dw

Best ResponseYou've already chosen the best response.1the '6's on the left side divide to 1 and cancel out more or less the 24/6 on the right side becomes 4 dw:1438647326597:dw

Best ResponseYou've already chosen the best response.1you have to follow PEMDAS in reverse 4b + 12 means 4*b + 12 the first thing we undo is the +12
