#### Work Step by Step

Add the equations to eliminate y.
$3x+3y=\ \ 27$
$\underline{\ x-3y=-11}$
$4x\ \ \ \ \ \ \ \ =\ \ \ 16$
Solve for x.
$4x=16$
$4x\div4=16\div4$
$x=4$
Substitute 4 for x in either equation and solve for y.
$x-3y=-11$
$4-3y=-11$
$4-3y-4=-11-4$
$-3y=-15$
$-3y\div-3=-15\div-3$
$y=5$
