Answer:

Step-by-step explanation:

<u>Multiplying both sides by 2</u>


<u>Subtracting 36 to both sides</u>


<u>Dividing both sides by 4</u>

OR

7(x+4)=0
7x+28=0
7x=-28
X=-28/7
X=-4
Answer: Y = -10
Step-by-step explanation:
-x + y = -27
-17 + y = -27
+17 +17
Y = -10
You can also check your work by plugging in the X and Y values and it should equal -27 . So -17 + -10 equals -27.
