Answer:

Steak burgers = $4.50

Fries = $2.25

Step-by-step explanation:

Steak burgers = x; fries = y

-2 (3x + 2y = $18)

3  (2x + 3y = $15.75)

-6x - 4y = -36

6x + 9y = 47.25

5y = 11.25

÷5    ÷5

y = $2.25

3x + 2y = 18

3x + 2( 2.25 ) = 18

3x + 4.5 = 18

     -4.5   -4.5

3x = 13.5

÷3     ÷3

x = $4.50

I hope this helps!
