Answer:

x = 1

y = 1

Step-by-step explanation:

y = x + 4

2x + 3y = 17

Since they gave us the value of "y" we can use that and substitute it into the equation to find what "x" is.

2x + 3y = 17

2x + 3 ( x + 4 ) = 17

Distributive Property

2x + 3 * x + 3 * 4 = 17

2x + 3x + 12 = 17

Combine Like Terms ( 2x and 3x)

5x + 12 = 17

Subtract 12 on both sides of the equation

5x + 12 - 12 = 17 - 12

5x = 5

Divide by 5 on both sides to isolate the variable

5x/5 = 5/5

x = 1

Now that we have what "x" is, we can substitute that into one of the equations to get the value of "y"

y = x + 4

y = 1 + 4

y = 5

x = 1

y = 5

( x, y )

The sum of two numbers is 25. Twice the first number minus the second is 6. Find the numbers.

Answers

Answer:

Step-by-step explanation:

x + y = 25

2x - y = 6           Solve for y in this the second equation. Add y to both sides

2x  = 6 + y         The ys on the left cancel. Subtract 6 from both sides.

2x - 6 = y

Put this value of y into the first equation

x + y = 25

x + 2x - 6 = 25      Combine on the left

3x - 6 = 25           Add 6 to both sides.

3x = 25 + 6           Combine the right

3x = 31                   Divide by 3

x = 31 / 3            

x = 10.333333

x + y = 25

10.33333 + y = 25  Subtract 10.33333

y = 25 - 10.333333

y = 14.666666

x + y = 25

10.33333 + 14.66666

25 approximately.

2x - y = 6

2*10.33333 - 14.66666

20.66666 - 14.66666

6

You should note that those numbers are repeating decimals

2x - 6 = y

LIFE

I wonder what it's all about, and why
We suffer so, when little things go wrong?
We make our life a struggle,
When life should be a song.

Our troubles break and drench us,
Like spray on the cleaving prow
Of some trim Gloucester schooner.
As it dips in a graceful bow.

Our troubles break and drench us
But like that cleaving prow,
The wind will fan and drys us.
And we'll watch come other bow.

But why does sorrow drench us
When our fellow passes on?
We just exchanged life's dreary dirge
For an eternal life of song.

What is the inborn human trait
That frowns on a life of song?
That makes us weep at the journey's end,
When the journey was oft-times wrong?

Weep when we reach the door
That opens to let us in,
And brings to us eternal peace.
As it closes again in sin.

Millions have gone before us,
And millions will come behind.
So why do we fight
At a fate both wise and kind.

We hang into a jaded life
A life full of sorrow and pain.
A life that warps and breaks us,
And we try to run through it again and again.​
