Answer: y=-5x-2
Step-by-step explanation:
Answer:
y = - 8
Step-by-step explanation:
y - 16 - 3y = 0
Group like terms
y - 3y - 16 = 0
Add similar elements: y - 3y = - 2y
- 2y - 16 = 0
Add 16 to both sides
- 2y - 16 + 16 = 0 + 16
Simplify
- 2y = 16
Divide both sides by - 2
= ![\frac{16}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B-2%7D)
Simplify
: y
![\frac{-2y}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2y%7D%7B-2%7D)
Apply the fraction rule: ![\frac{-a}{-b} = \frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7B-a%7D%7B-b%7D%20%20%3D%20%5Cfrac%7Ba%7D%7Bb%7D)
= ![\frac{2y}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2y%7D%7B2%7D)
Divide the numbers: ![\frac{2}{2} = 1](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B2%7D%20%20%3D%201)
= y
Simplify
: - 8
![\frac{16}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B16%7D%7B-2%7D)
Apply the fraction rule: ![\frac{-a}{-b} = \frac{a}{b}](https://tex.z-dn.net/?f=%5Cfrac%7B-a%7D%7B-b%7D%20%20%3D%20%5Cfrac%7Ba%7D%7Bb%7D)
![-\frac{16}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B16%7D%7B2%7D)
Divide the numbers:
= 8
= - 8
y = - 8
It should be :
1/3(x + 18) = 7
1/3x + 6 = 7
1/3x + 6 - 6 = 7 - 6
1/3x = 1
x = 3
