3b+7.1=2.5b+11.5 First, you'd take 2.5b and subtract it from 3b 3b-2.5b+7.1=11.5 Simplify: .5b+7.1=11.5 then, you would take 7.1, and since it is positive, subtract it from 11.5 .5b=11.5-7.1 Simplify: .5b=4.4 Lastly, you'd take 4.4 and divide it by .5, leaving the unknown factor alone. b=4.4/.5 Final answer: b=8.8
