5=\frac{-3\times 6}{5}+b
Express -\frac{3}{5}\times 6 as a single fraction.
5=\frac{-18}{5}+b
Multiply -3 and 6 to get -18.
5=-\frac{18}{5}+b
Fraction \frac{-18}{5} can be rewritten as -\frac{18}{5} by extracting the negative sign.
-\frac{18}{5}+b=5
Swap sides so that all variable terms are on the left hand side.
b=5+\frac{18}{5}
Add \frac{18}{5} to both sides.
b=\frac{25}{5}+\frac{18}{5}
Convert 5 to fraction \frac{25}{5}.
b=\frac{25+18}{5}
Since \frac{25}{5} and \frac{18}{5} have the same denominator, add them by adding their numerators.
b=\frac{43}{5}
Add 25 and 18 to get 43.
