<h2>Steps:</h2>

So with this system of equations, I will be using the elimination method. With the two equations, add them together and you will get:

2x=6

Since the y-variable has been eliminated, we can solve for x. With this, divide both sides by 2:

x=3

Now that we know the value of x, substitute it into either equation to solve for y:

3+y=2\\y=-1\\\\3-y=4\\-y=1\\y=-1

<h2>Answer:</h2>

<u>In (x,y) form, your answer is (3,-1).</u>

Answer:

x=3, y=-1

Step-by-step explanation:

x+y = 2  

x -y =4  



I will use elimination to eliminate the variable y.  Add the two equations together.

x+y = 2  

x -y =4  

-------------

2x = 6

Divide each side by 2

2x/2 = 6/2

x = 3

But we still don't know y

x+y =2

Substitute x=3 into the equation

3+y =2

Subtract 3 from each side

3-3 +y =2-3

y =-1

Hello there! I am EnjoyingLife, and I hope you find my answer helpful.

First of all, since all books cost less than $5, the most expensive a book could be is $4.99 (remember, less than, not less than or equal to)

Now, let's write an inequality to represent the cost of books.

We know that all books cost less than $5.

We have a sign for "less than". It's "<"

Thus,

p<5

Hope it helps!

Have an awesome day!

Good luck!
