Answer:

1 2/3

Step-by-step explanation:

If you do the things in the order which would be 2/6*4 (because that is how the order of operations would be) that equals 1 1/3 in fractions.  So to get to B, you need to find what equals 3 so you would do 3- 1 1/3 and that would give you 1 2/3.

3=2/6*4+b

3=4/3+b

3-4/3=b

B=2 2/3
