Eva is at a sushi restaurant. She ordered 2 pieces of squid for a total of $3.50, 1 piece of eel for $3.25, 3 pieces of tuna for
earnstyle [38]
2 pieces of squid = $3.50 
Therefore 1 piece of squid = $1.75 (3.50÷2)

1 piece of eel = $3.25

3 pieces of tuna = $6.75
Therefore 1 piece of tuna = $2.25 (6.75÷3)

4 pieces of crab = $8.00 
Therefore 1 piece of crab = $2 (8÷4)

Put them in order of price and you get 

$1.75 , $2 , $2.25 , $3.25

Solve this system of equations using the elimination method.
Ray Of Light [21]

Answer:

(6, -9)

Step-by-step explanation:

Our system of linear equations is:

6x + 2y = 18

-4x - 2y = -6

When we solve by elimination, we're essentially "eliminating" a variable so that we can solve for other more easily. Here, let's eliminate the y variable by adding the two equations together:

    6x + 2y = 18

+   -4x - 2y = -6

____________

    2x  +  0y = 12

x = 12/2 = 6

Plug this back into one of the original equations to find y:

-4x - 2y = -6

-4 * 6 - 2y = -6

-24 - 2y = -6

-2y = 18

y = -9

The solution is (6, -9).
