    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
