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
[tex]\frac{-2y}{-2}[/tex] = [tex]\frac{16}{-2}[/tex]
Simplify [tex]\frac{-2y}{-2}[/tex]: y
[tex]\frac{-2y}{-2}[/tex]
Apply the fraction rule: [tex]\frac{-a}{-b} = \frac{a}{b}[/tex]
= [tex]\frac{2y}{2}[/tex]
Divide the numbers: [tex]\frac{2}{2} = 1[/tex]
= y
Simplify [tex]\frac{16}{-2}[/tex]: - 8
[tex]\frac{16}{-2}[/tex]
Apply the fraction rule: [tex]\frac{-a}{-b} = \frac{a}{b}[/tex]
[tex]-\frac{16}{2}[/tex]
Divide the numbers: [tex]\frac{16}{2}[/tex] = 8
= - 8
y = - 8
