color(red)( b = - 60

#### Explanation:

$- \frac{3}{5} b + \textcolor{red}{7} + \frac{2}{5} b = 19$

Making the denominator of the L.H.S equal:
$- \frac{3}{5} b + \textcolor{red}{\frac{35}{5}} + \frac{2}{5} b = 19$

$\frac{35 - 3 b + 2 b}{5} = 19$
$35 - b = 19.5$
$35 - b = 95$
$- b = 60$
color(red)( b = - 60
