Amelie solves the following system of equations.
x+y=20
3x-3y+30
which values of x and y satisfy this system of equations?
x = 0, y = 20
x = 5, y = 15
x = 10, y = 0
x = 15, y = 5

x = 15, y = 5

Step-by-step explanation:

The given system is

Multiplying 3 on both sides of equation (1), we get

Now, adding (2) and (3), we get

Substitute the value of x in (1), we get

Hence, the of x and y satisfy this system of equations is x = 15, y = 5.

My name is Yoshikage Kira. I'm 33 years old. My house is in the northeast section of Morioh, where all the villas are, and I am not married. I work as an employee for the Kame Yu department stores, and I get home every day by 8 PM at the latest. I don't smoke, but I occasionally drink. I'm in bed by 11 PM, and make sure I get eight hours of sleep, no matter what. After having a glass of warm milk and doing about twenty minutes of stretches before going to bed, I usually have no problems sleeping until morning. Just like a baby, I wake up without any fatigue or stress in the morning. I was told there were no issues at my last check-up. I'm trying to explain that I'm a person who wishes to live a very quiet life. I take care not to trouble myself with any enemies, like winning and losing, that would cause me to lose sleep at night. That is how I deal with society, and I know that is what brings me happiness. Although, if I were to fight I wouldn't lose to anyone. ゴ Killer Queen Intensifies ゴ
