Answer:
![\large \boxed{{y=18}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%7By%3D18%7D%7D)
Step-by-step explanation:
![1(y+3)=2(y+-4)+- 7](https://tex.z-dn.net/?f=1%28y%2B3%29%3D2%28y%2B-4%29%2B-%207)
Expand brackets.
![y+3=2y-8+- 7](https://tex.z-dn.net/?f=y%2B3%3D2y-8%2B-%207)
Simplify.
![y+3=2y-15](https://tex.z-dn.net/?f=y%2B3%3D2y-15)
Add -y and 15 on both sides.
![y+3-y+15=2y-15-y+15](https://tex.z-dn.net/?f=y%2B3-y%2B15%3D2y-15-y%2B15)
Simplify.
![3+15=2y-y](https://tex.z-dn.net/?f=3%2B15%3D2y-y)
![18=y](https://tex.z-dn.net/?f=18%3Dy)

Answer:
Yes
Step-by-step explanation:
The standard form for a quadratic equation in the US has the terms in decreasing order by power on the left of the equal sign, and the right side zero. Preferably, the leading coefficient is positive. This might also be called "general form." Elsewhere, the "standard form" may be different.
