2x - y = -2
x = 14 + 2y
Plug in the x equation
2(14+2y) - y = -2
Distribute
28 + 4y - y = -2
Combine variables
28 + 3y = -2
Subtract 28 on both sides
3y = -30
Divide the y
y = -10
Answer:
Step-by-step explanation:

Answer:
House A
Step-by-step explanation
For house A:
divide 125,260 by to to find 10%.
10% = 12,526.The you divide this by two to get 5%.
5% = 6,263.Next add the original figure with the 5%. To makes things simpler insted of adding 5% percent twice(since were calculating for two years) just add the 10% to the original figure you get:
125,260 + 12,526= $137,786
For house B:
This is a little different than before. Find ten percent then 5 percent.
10%= 12,016
5%=6,008.Next to find 1% divide the 10% again!
1%-1,201.6,After add the five percent and 1% to find 6%.
6%=7,209.6. Multiply the 6% by 2 to find the price for 2 years.Next add the original number to the 12%.
12%=14,419.2
17,419.2+120,160= $134,579.2
In conclusion:
Compare the prices-
A=$137,786
B=$134,579.2
House A earns more money after two years.
