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
