Answer:
All real numbers
Step-by-step explanation:
![-2(y - 4) = 20 - 2y - 12](https://tex.z-dn.net/?f=-2%28y%20-%204%29%20%3D%2020%20-%202y%20-%2012)
Start by distributing -2 inside the parentheses.
![-2y + 8 = 20 - 2y - 12](https://tex.z-dn.net/?f=-2y%20%2B%208%20%3D%2020%20-%202y%20-%2012)
Combine like terms on the right side of the equation.
![-2y + 8 = 8 - 2y](https://tex.z-dn.net/?f=-2y%20%2B%208%20%3D%208%20-%202y)
Subtract 8 from both sides of the equation.
![-2y =- 2y](https://tex.z-dn.net/?f=-2y%20%3D-%202y)
Divide both sides by -2 to isolate y.
![0=0](https://tex.z-dn.net/?f=0%3D0)
This is a true statement, so there are infinite solutions.
2.6 because the next number is 1 which is less than 5 so it is rounded down, if it was 2.65 or higher you would round up to 2.7
Answer:
(2, 13)
(-7, -5)
Step-by-step explanation:
Easiest and fastest way to do this is to graph the systems of equations and analyze the graph where the 2 graphs intersects.
