Question 1178314
--------------------
x - 2y = - 1
3y = x + 4
--------------------


And what?


{{{system(x-2y=-1,3y=x+4)}}}


{{{system(x-2y=-1,-x+3y=4)}}}


ADD corresponding members and eliminate x.
{{{(-2y)+3y=(-1)+4}}}

{{{highlight(y=3)}}}---------------Now use this, in either equation, to find x.
