neonumbrella5115 · Answer

Okay, no solution is not the answer.  To do substitution, first you need to solve each equation for e.  Can you do that?

narissa · Answer

ok 3,-1

Yes that is the correct answer!  Good job!

Look here it asking to use substitution method which is express one variable in terms of another variable 
Ex:
$$y=x+2$$
$$y+2=-4$$
So what you have to do is to remove each y and plug (x+2) instead
$$(x+2)+2=-4$$
$$x+4=-4$$
$$x=-8$$
and then plug x-value into very first equation to get y-value
