No it isn't. 5x is 5*x. not plus. so x would be 19 since 5*19=95
Answer:
6/x^4

Answer:
Some of the other answers are good examples of solving a system of three equations in three unknowns, which is what this problem is asking. Though the simplest way to solve this problem is actually to notice that, if we sum the three equations, we get:
X + Y = 10
X + Z = 20
+ Y + Z = 24
----------------
2X + 2Y + 2Z = 54
Factoring out the 2, we have 2(X + Y + Z) = 54, and dividing both sides by 2 reveals that X + Y + Z = 27.

Answer: 11,232,000
This result is a single number slightly over 11 million

Work Shown:
Throughout all of this, order does matter (eg: ABC is different from BCA)
Focus on the letters for now
There are 26 letters total.
The first slot has 26 choices
The second slot has 25 choices (since we can't reuse whatever is in slot1)
The third slot has 24 choices
For just the letters only, we have 26*25*24 = 15600 permutations
Since we'll use this number later, let's call this M = 15600
---------------------
Now onto the numbers. There are 10 digits total
For slot 1 we have 10 choices
For slot 2 we have 9 choices
For slot 3 we have 8 choices
For just the numbers only, we have 10*9*8 = 720 permutations
Since we'll use this number later, let's call this N = 720
---------------------
Now multiply M and N
M*N = 15600*720 = 11,232,000
So we can generate 11,232,000 serial numbers
