#{(5x-3y=-14),(x-3y=2):}#

by subtracting the second equation from the first equation,

#=> 4x=-16#

by dividing by 4,

#=> x=-4#.

By plugging #x=-4# into the second equation,

#(-4)-3y=2#

by adding #4#,

#=> -3y=6#

by dividing by #-3#,

#=> y=-2#

Hence, the solution is: #(x,y)=(-4,-2)#.

I hope that this was helpful.
