Solve each system by elimination. First clear denominators.

3x/2 +y/2=-2

x/2 +y/2=0

Multiply both equations by 2:
$\displaystyle\left\{\begin{array}{ll}3x+y=-4\\x+y=0\end{array}\right.$

Substract the second equation from the first to eliminate y:

$2x=-4\Rightarrow x=-2$

Replace x in the second (or first) equation and find y.
