Answer:
![6(7-3y)+6(y+1) = - 12y + 48](https://tex.z-dn.net/?f=6%287-3y%29%2B6%28y%2B1%29%20%3D%20-%2012y%20%2B%2048)
Step-by-step explanation:
Given
![6(7-3y)+6(y+1)](https://tex.z-dn.net/?f=6%287-3y%29%2B6%28y%2B1%29)
Required
Determine the equivalent expression
We have:
![6(7-3y)+6(y+1)](https://tex.z-dn.net/?f=6%287-3y%29%2B6%28y%2B1%29)
Open brackets
![6(7-3y)+6(y+1) = 6 * 7 - 6 * 3y + 6 * y + 6 * 1](https://tex.z-dn.net/?f=6%287-3y%29%2B6%28y%2B1%29%20%3D%206%20%2A%207%20-%206%20%2A%203y%20%2B%206%20%2A%20y%20%2B%206%20%2A%201)
![6(7-3y)+6(y+1) = 42 - 18y + 6y + 6](https://tex.z-dn.net/?f=6%287-3y%29%2B6%28y%2B1%29%20%3D%2042%20-%2018y%20%2B%206y%20%2B%206)
Collect like terms
![6(7-3y)+6(y+1) = - 18y + 6y + 6 + 42](https://tex.z-dn.net/?f=6%287-3y%29%2B6%28y%2B1%29%20%3D%20-%2018y%20%2B%206y%20%2B%206%20%2B%2042)
![6(7-3y)+6(y+1) = - 12y + 48](https://tex.z-dn.net/?f=6%287-3y%29%2B6%28y%2B1%29%20%3D%20-%2012y%20%2B%2048)
Answer:
e = ![-\frac{1}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
1. ![\frac{4}{3} = -6e -\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%20%3D%20-6e%20-%5Cfrac%7B5%7D%7B3%7D)
2. 4/3 - (-5/3)
3. you get 9/3 which can be converted to 3
4. 3 = -6e
5. divide -6 on both sides of the equation and e will equal to -1/2
