Well, what I would do is line it up so you can cancel things out. I.e.:
(3x*2y-2)3
(9xy*3)3
Both of the 3s can cancel out
3x*2y-2
9xy*3
2y-2
3y*3
2y/3y-2/3=2/3-2/3=0

Answer:
-13
Step-by-step explanation:
The more negative the number, the colder it is
-13 is more negative than -10
-13 < -10
-13 is colder
X= be coffee
Y=be donuts
Set up equations
10x+5y=16.50
5x+10y=14.25
Now multiply first equation by -2 to get a negative
(-2)10x+5y(-2)=16.50(-2)
-20x-10y=-33
Now put both equations to solve for x
-20x-10y=-33
5x+10y=14.25
___________
-15x. = -18.75
Now divide -15 bith sides to get x alone
X= -18.75/-15
X= 1.25
The cost of each coffee cup$1.25
