X+2y=3 x-y=3 x=? y=?

Mathematics

alexgriva [62]3 years ago

Answer:

x = 3

y = 0

Step-by-step explanation:

x + 2y = 3 ---------eqn 1

x - y = 3 --------eqn 2

Using eqn 2 to find the value of y

x - y = 3

Making y the subject of the formula

x - 3 = y

y = x - 3

Substitute the value of y into eqn 1

x + 2y = 3

x + 2(x - 3) = 3

Open the bracket

x + 2x - 6 = 3

3x - 6 = 3

3x = 3 +6

3x = 9

Divide both sides by 3, to get value of x

3x/3 = 9/3

x = 3

To get the value of y, use eqn 2

x - y = 3

3 - y = 3

3 - 3 = y

y = 0

Hint, to know maybe the values are correct, insert the values into the equation

Let's use eqn 2

x - y = 3

x = 3

y = 0

Insert into the equation

x - y = 3

3 - 0 = 3

Our values are correct

As the world I’m heading towards and matching up to is getting bigger  

It makes me feel an emptiness somehow  

What part it is, even if the shape is maybe like this  

Even when myself can’t come to know it  

As if solving up the scattered pieces  

We are matching up our stories  

Inside the empty spot in my heart, there’s a piece called you taking place  

I just know it at first glance I saw you  

You’re my missing puzzle piece  

Finally I solved it  

You filled every piece of my heart, even the scarred part of it to the fullest  

And somehow, you’ve become my everything  

My missing puzzle piece  

The fact that I have a flaw,  

The truth that I am imperfect All of it makes me feel small  

But in between those gaps  

We can fill one another with it  

So I don’t even realized that it was empty  

“Hello, it’s been so long, isn’t it?”  

The small piece that I put in my pocket and carry around everywhere  

Please be with me so it can be fuller and prettier  

After I met you, I’m able to draw a bigger picture  

You’re my missing puzzle piece  

Finally I solved it  

You filled every piece of my heart, even the scarred part of it to the fullest  

And somehow, you’ve become my everything  

My missing puzzle piece  

My missing puzzle piece  

More than having everything, Not losing that one thing is more important  

Through you, I came to know that  

You’re my missing puzzle piece  

Very dazzling  

It becomes one scene inside the world that I’ve been trying to put together alone

Like the hands that are interlocking tight together,

Because without you, it can’t be completed  

So that we won’t lose each other,  

My missing puzzle piece  

My missing puzzle piece

a Members of a soccer team raised $1530.50 to go to a tournament. They rented a bus for $1164.50 and budgeted $30.50 per player
Helen [10]

The number of players that can be taken to the tournament is 12 players.

The equation that can be used to represent the total amount spent by the soccer team is:

Total amount spent = cost of rented bus + (cost per meal x total number of players)

$1530.50 = $1164.50 + $30.50x

Where: x = total number of player

In order to determine the value of x, the following steps would be taken:

Combine similar terms

$1530.50 - $1164.50 = $30.50x

$366 = $30.50x

Divide both sides of the equation by 30.50

x = $366 / $30.50

x = 12 players
