Answer:
Step-by-step explanation:
-8, 2
You can split this shape into two shapes; a rectangle on top and a horizontal rectangle underneath. The top rectangle would be 4 x 2 = 8 square units, and the bottom rectangle would be 7 x 1 (3 - 2) = 7 square units. Now you just add these to get 15 square units. I hope this helps!

Answer:
The first step is to replace the value of x from the first equation with x in the second equation:
x=y-7
3x+15y=-1
3(y-7)+15y=-1
3y-21+15y=-1
18y=-1+21
18y=20
y=
= ![\frac{10}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B9%7D)
x=
![- 7](https://tex.z-dn.net/?f=-%207)
x=![- \frac{53}{9}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B53%7D%7B9%7D)
