Answer:

y = 1

x = -3

Step-by-step explanation:

9x + 2y = 3

-x - y = -12 (multiply second equation with 9)

9x + 2y = 3

-9x - 9y = - 108 (add these to up)

-7y = -105

y = 15 use this to find x

9x + 2y ➡ 9x + 30 = 3 ➡ 9x = -27 ➡ x = -3

What is the area, in square units, of the polygon shown here?
WITCHER [35]
You just need to break it into parts. The first rectangle is the tall one. To find the area of this one, just multiply the tall side by the short side on top.

8 x 2 = 16

The second rectangle is the long one on the bottom. If the whole bottom side is 5 units, then you need to subtract 2 from that. 

3 x 1 = 3

16 + 3 = 19 units, so the area of the entire shape would be 19 units^2. Hope this helps! :)
