<PRE><B>Question 242818</B>
Solve for y in each equation:
 y=-x+4
y=-x-4


Are you allowed to use a graphing calculator?  If so, there it is:

{{{graph(300,300,-10,10,-10,10,-x+4,-x-4) }}}


The lines are quite obviously PARALLEL, so there is NO SOLUTION.  Sometimes this is written that the system of equations is INCONSISTENT!
