6x + 3y = 15
y = 3x - 5
6x + 3(3x - 5) = 15
6x + 9x - 15 = 15
15x -15 + 15 = 15 + 15
15x = 30
15x/15 = 30/15
x = 2
6x + 3y = 15
6(2) + 3y = 15
12 + 3y = 15
12 - 12 + 3y = 15 - 12
3y = 3
3y/3 = 3/3
y = 1
The value of y is 1

Answer:
The number of units sold increased by ![\mathbf{11.2\%}](https://tex.z-dn.net/?f=%5Cmathbf%7B11.2%5C%25%7D)
Step-by-step explanation:
Vacuum dealer sold units in 2011 = 420
Vacuum dealer sold units in 2012 = 467
We need to find percent increase or decrease
Since, In 2012 units sold are greater than 2011, so there will be percent increase.
The formula used is: ![Percent\:Increase=\frac{New\:Value-Original\:Value}{Original\:Value}\times 100](https://tex.z-dn.net/?f=Percent%5C%3AIncrease%3D%5Cfrac%7BNew%5C%3AValue-Original%5C%3AValue%7D%7BOriginal%5C%3AValue%7D%5Ctimes%20100)
We have New Value (Units sold in 2012) = 467
Original Value (Units sold in 2011) = 420
Percent increase is:
![Percent\:Increase=\frac{New\:Value-Original\:Value}{Original\:Value}\times 100\\Percent\:Increase=\frac{467-420}{420}\times 100\\Percent\:Increase=\frac{47}{420}\times 100\\Percent\:Increase=11.2\%](https://tex.z-dn.net/?f=Percent%5C%3AIncrease%3D%5Cfrac%7BNew%5C%3AValue-Original%5C%3AValue%7D%7BOriginal%5C%3AValue%7D%5Ctimes%20100%5C%5CPercent%5C%3AIncrease%3D%5Cfrac%7B467-420%7D%7B420%7D%5Ctimes%20100%5C%5CPercent%5C%3AIncrease%3D%5Cfrac%7B47%7D%7B420%7D%5Ctimes%20100%5C%5CPercent%5C%3AIncrease%3D11.2%5C%25)
So, The number of units sold increased by ![\mathbf{11.2\%}](https://tex.z-dn.net/?f=%5Cmathbf%7B11.2%5C%25%7D)
