What this solving system of equations?
x+y=-3
y=x^2+4x+1

x = -4,  y = 1

x = -1,   y = -2

Step-by-step explanation:

(1)     x + y = -3                  (2)    y =

             y = -x - 3                   -x - 3 =  

                                                    (x + 4)(x + 1) = 0

                                                         x = -4  or x = -1

            y = -(-4) - 3 = 4 - 3 = 1

            y = -(-1) - 3 = 1 - 3 = -2

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
