Use the Substitution method to solve the system of equations.
x + y = -4
x - y = 2
solve for x in the second equation.
Put that in for x in the first equation:
(y+2) + y = -4
solve for y. Then, x= y+2
i don't get it.How did you get that?What does x equal?
re read my post. I tell you how I got it. you will have then to solve for x, then, put that value of x back in the equation, and solve for y. Post your work.
does x =5?
i have been trying to
figure out how to solve this
problem but i just can't.
it seems so difficult.
i have already seen some
examples but i still don't
SOLVE USING THE SUBSTITUTION METHOD.
