Solving the system of equations, it is found that x = 3, that is, there are 3 128 MB memory sticks.
--------------------
We want to solve for x, thus, in the first equation, we write y as a function of x, that is:

Replacing in the second equation:

Answer:
Josie bought 40 adult tickets and 32 children tickets.
Step-by-step explanation:
x+y=72
22x+10y=1200
-----------------------
x=72-y
22(72-y)+10y=1200
1584-22y+10y=1200
1584-12y=1200
12y=1584-1200
12y=384
y=384/12=32
x+32=72
x=72-32=40
x=40, y=32. (40, 32)
