#x = 6 2/3#
#y = -24 2/3#

Explanation:

You have 2 equations:
#x+y = -18#
#-14x-3y=-18#

Solve for y in each(so we can input it into our calculator)

#x+y = -18#

#y = -18-x#

and

#-14x-3y=-18#

#-3y = -18+14x#

#y(-3) =14x-18#

#y = (14x-18)/(-3)#

Graph the two equations:
#y = (14x-18)/(-3)#

#y = -18-x#

The intersection point of these two lines is our answer.
