Two bottled waters and an order of cheese nachos costs $5.50. three bottled waters and two orders of cheese nachos costs $9.50

what does it ask for?

Answer: You might have messed up the question

Here is the answer based on your question

W (Bottled water) = 7/2$

N (Cheese Nachos) = - 1/2$

Step-by-step explanation:

2W + 3N = $5.50

3W + 2N = $9.50

Find the common number and subtract them. In order to find isolate the water bottles or nachos. I will do water bottles

15 (2W + 3N = $5.50)

10 (3W + 2N = $9.50)

30w + 45N = $82.5

Minus

30W + 20N = $90

= 25N = - 12.5

N = - 1/2$

Substitute for N

3W + 2 (-1/2) = 9.5

3w - 1 = 9.5

3w - 10.5

w = 7/2$
