Answer:

x = 5 and y = 3

Step-by-step explanation

y crosses out so you are left with

4x = 20 (divide by 4)

x = 5

plug x into either equation

5 + y = 8 (subtract 5)

y = 3

How do u do this problem
atroni [7]
Alexis and 3 friends buy:
-Pretzel $4.
-Sauce $1
-Drink $2

First we would multiply all the food prices by 4, since there is 4 people in total.
4 x 4 = $16
1 x 4 = $4
2 x 4 = $8

Now we're adding all the prices together. 
16 + 4 + 8 = $28

At this point, we're going to make the expression, using all the steps that we did.
( 4 x 4 ) + ( 1 x 4 ) + ( 2 x 4 )

We used parenthesis to show that those expressions need to be done first before anything else.

This is how we make an expression and we find the total answer.

The expression would be: ( 4 x 4 ) + ( 1 x 4 ) + ( 2 x 4 )
The total cost would be: $28

Hope this helps!~
