L+R=19
L-R=9

2L=28
L=14

(14)+R=19
R=5

L=14
R=5

Check:
(14)+(5)=19
(14)-(5)=9

What is the length of the longest side of a triangle that has the vertices (-5, 6), (-5, -2), and (1, -2)?

Check the picture below.

$\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\
\begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ -5 &,& 6~) 
% (c,d)
&&(~ 1 &,& -2~)
\end{array}~~~ 
% distance value
d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}
\\\\\\
d=\sqrt{[1-6]^2+[-2-(-5)]^2}\implies d=\sqrt{(1-6)^2+(-2+5)^2}
\\\\\\
d=\sqrt{(-5)^2+3^2}\implies d=\sqrt{25+9}\implies d=\sqrt{34}$
