2=5b+4
Subtract 1 from 5 to get 4.
5b+4=2
Swap sides so that all variable terms are on the left hand side.
5b=2-4
Subtract 4 from both sides.
5b=-2
Subtract 4 from 2 to get -2.
b=\frac{-2}{5}
Divide both sides by 5.
b=-\frac{2}{5}
Fraction \frac{-2}{5} can be rewritten as -\frac{2}{5} by extracting the negative sign.
