Verified Answer :

5(3y-16)-3y = -20
15y-80-3y = -20
12y = 60
y = 5

\(5x - 3y = -20\)
\(x = 3y - 16\)

Plug in 'x' into the first equation:

\(5 (3y - 16) - 3y = 20\)
\(15y - 80 - 3y = -20\)
\(12y = 60\)
\(y = 5\) 

Plug in 'y' into the second equation to get 'x':

\(x = 3y - 16\)
\(x = 3(5) - 16\)
To get \(x = -1\)

\(y = 5\)
\(x = -1\)
