Answer: 91.5
Step-by-step explanation:
Answer:
C) 3(x + 3y + 5)
D) 3x + 3(3y +5)
The answer is 3 29/36
5 3/12 = 5 9/36
1 4/9 = 1 16/36
So the answer equation is 5 9/36 - 1 16/36
down: 4 45/36 - 1 16/36 = 3 29/36

Answer:
![\boxed{\boxed{\sf x=-3}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Cboxed%7B%5Csf%20x%3D-3%7D%7D)
Step-by-step explanation:
![\sf y = -3x - 2](https://tex.z-dn.net/?f=%5Csf%20y%20%3D%20-3x%20-%202)
![\sf y=7](https://tex.z-dn.net/?f=%5Csf%20y%3D7)
We'll substitute y into the equation:
![\sf 7 = -3x - 2](https://tex.z-dn.net/?f=%5Csf%207%20%3D%20-3x%20-%202)
Switch sides:
![\sf -3x-2=7](https://tex.z-dn.net/?f=%5Csf%20-3x-2%3D7)
Add 2 to both sides
![\sf -3x-2+2=7+2](https://tex.z-dn.net/?f=%5Csf%20-3x-2%2B2%3D7%2B2)
![\sf -3x=9](https://tex.z-dn.net/?f=%5Csf%20-3x%3D9)
Divide both sides by -3:
![\sf \cfrac{-3x}{-3}=\cfrac{9}{-3}](https://tex.z-dn.net/?f=%5Csf%20%5Ccfrac%7B-3x%7D%7B-3%7D%3D%5Ccfrac%7B9%7D%7B-3%7D)
![\sf x=-3](https://tex.z-dn.net/?f=%5Csf%20x%3D-3)
Therefore, the value of x/solution is -3
