Question 1181677
.
<pre>

By dividing the terms by (-2), you see that the second equation is equivalent to


    3x - 2y = 5.


Thus the two original equations are equivalent to single equation


    3x - 2y = -5.


So they represent the same straight line and have infinitely may solutions


    y = {{{(3x + 5)/2}}},


where x is any real number.
