%283b%29%2F5+%2B+%282b+-+5%29%2F3+=+-4

Put parentheses around all the terms:

%28%283b%29%2F5%29+%2B+%28%282b+-+5%29%2F3%29+=+%28-4%29

The LCD is 15 so multiply every term by 15

15%28%283b%29%2F5%29+%2B+15%28%282b+-+5%29%2F3%29+=+15%28-4%29

On the first term the 5 cancels into the 15 giving 3
On the second term the 3 cancels into the 15 giving 5
On the right we get -60

3%283b%29+%2B+5%282b-5%29+=+-60

9b+%2B+10b+-+25+=+-60

19b+-+25+=+-60

19b+=+-60%2B25

19b+=+-35

b+=+-35%2F19
