Answer:
See below.
Step-by-step explanation:
6x + 4y = 37 [These are the correct equations]
2x + 3y = 16.50
======
I don't see any question concerning the individual prices, x and y, but here is the answer:
-6x -9y = - 49.50 [Multiply the second equation by -3]
6x + 4y = 37 [now add it to the first equation]
-5y = -12.50
y = 2.50 $2.50 is the price of one drink
Use this value of y in either equation to find x, the price of 1 slice of pizza.
6x + 4y = 37
6x + 4*(2.50) = 37
6x + 10 = 37
6x = 27
x = 4.50 $4.50 is the price of one slice of pizza
