Solve the compound inequality 6b < 24 or 4b + 12 > 4. b < 4 or b > −2 b < 4 or b > 4 b < 4 or b > 2 b > 4 or b < −2

Focus on just 6b < 24 for now. How would you isolate b here?

jimthompson5910 (jim_thompson5910):

the 6b means "6 times b" we need to undo the multiplication so we divide both sides by 6 to isolate b |dw:1438647301431:dw|
