Answer:
![(- 8)](https://tex.z-dn.net/?f=%20%28-%208%29)
Step-by-step explanation:
The equation would be
![20x = - 160 \\ \frac{20x}{20} = \frac{160}{20} \\ x = 8](https://tex.z-dn.net/?f=20x%20%3D%20%20-%20160%20%5C%5C%20%20%5Cfrac%7B20x%7D%7B20%7D%20%3D%20%20%5Cfrac%7B160%7D%7B20%7D%20%20%20%5C%5C%20x%20%3D%208)
3x + 6 = 3x + 6
3x - 3x = 6 - 6
0 = 0
infinitely many solutions.
Little tip....if ur equation ends up like this : 0 = 0, or 2 = 2...or anything equal, it will have infinite solutions. If ur equation ends up like this : 2 = 4, or 5 = 7...or anything unequal, then it will have no solutions. If ur equation ends up like this : y = 2, or x = 10....then there will be one solution.
Do you still need help on this?
For this case we have the following expressions:
![2b + b\\3b](https://tex.z-dn.net/?f=2b%20%2B%20b%5C%5C3b)
For ![b = 1:](https://tex.z-dn.net/?f=b%20%3D%201%3A)
![2 (1) + 1 = 2 + 1 = 3\\3 (1) = 3](https://tex.z-dn.net/?f=2%20%281%29%20%2B%201%20%3D%202%20%2B%201%20%3D%203%5C%5C3%20%281%29%20%3D%203)
For ![b = 2:](https://tex.z-dn.net/?f=b%20%3D%202%3A)
![2 (2) + 2 = 4 + 2 = 6\\3 (2) = 6](https://tex.z-dn.net/?f=2%20%282%29%20%2B%202%20%3D%204%20%2B%202%20%3D%206%5C%5C3%20%282%29%20%3D%206)
For
:
![2 (3) + 3 = 6 + 3 = 9\\3 (3) = 9](https://tex.z-dn.net/?f=2%20%283%29%20%2B%203%20%3D%206%20%2B%203%20%3D%209%5C%5C3%20%283%29%20%3D%209)
For any number, the expressions will be equivalent because ![2b + b = 3b](https://tex.z-dn.net/?f=2b%20%2B%20b%20%3D%203b)
ANswer:
and
have the same value for b = 1,2,3
