To do this, you need to solve either one of the equations for y or x. I'm going to solve for y in the first equation:

6x + 3y = 9

Subtract 6x from both sides:

3y = 9 - 6x

Divide both sides by 3:

y = 3 - 2x

Now that you know what y is equal to, you can substitute it into the second equation:

2x + 3y = 1

2x + 3(3-2x) = 1

Distribute the 3:

2x + 9 - 6x = 1

Combine like terms:

9 - 4x = 1

Subtract 9 from both sides:

-4x = -8

Divide by -4:

x = 2

No substitute this 2 into either one of the equations to get y. I'm going to use the first:

6x + 3y = 9

6(2) + 3y = 9

12 + 3y = 9

Subtract the 12 from both sides:

3y = -3

Divide by 3:

y = -1

ANSWER:

x = 2

y = -1

You can always check by substituting the values into the equations.

Complete question is;

Many states run lotteries to raise money. A website advertises that it knows "how to increase YOUR chances of Winning the Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a "lucky" number to play, but maybe some numbers are luckier than others. Let's use a simulation to see how well this system works. To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number. Any value can be​ picked, but for this​ exercise, pick 1 as the lucky number. What proportion of the time do you​ win?

Answer:

10%

Step-by-step explanation:

We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.

This means the total number of single digits that could possibly be a winning one is 10.

Since we are told that only 1 can be picked, thus;

Probability of winning is; 1/10 = 0.1 or 10%
