7(6/7-b)+3/5b=2/5(b+5)
We move all terms to the left:
7(6/7-b)+3/5b-(2/5(b+5))=0
Domain of the equation: 7-b)!=0
We move all terms containing b to the left, all other terms to the right
-b)!=-7
b!=-7/1
b!=-7
b∈R
Domain of the equation: 5b!=0
b!=0/5
b!=0
b∈R
Domain of the equation: 5(b+5))!=0We add all the numbers together, and all the variables
b∈R
7(-1b+6/7)+3/5b-(2/5(b+5))=0
We multiply parentheses
-7b+3/5b-(2/5(b+5))+6/7*7=0
We calculate fractions
(735bb/(1225b^2b+(-(2*5b*7*7)/(1225b^2b+750b^2/(1225b^2b-7b=0
