Answer:
Step-by-step explanation:
The given information can be tabulated as follows:
Graphics G Printing P Total
X 3 2 5
Y 1 1 2
Available 21 19
We have the constraints as

Thus we have solutions as

Answer:
212
Step-by-step explanation:
<u>Rule</u>
- Subtract the 2nd number from the first to obtain the first digit(s) of the answer.
- Add the 2nd number to the 1st to obtain the last digit(s) of the answer.
5 - 3 = 2
5 + 3 = 8
Therefore: 28
9 - 1 = 8
9 + 1 = 10
Therefore: 810
8 - 7 = 1
8 + 7 = 15
Therefore: 115
6 - 2 = 4
6 + 2 = 8
Therefore: 48
7 - 5 = 2
7 + 5 = 12
Therefore: 212
Y= 2x-4
4x+Y=2
4x+2x-4=2
6x-4=2
+4=+4
6x=6
6/6X = 6/6 X=1
Y=2X-4
2(1)-4
Y=-2
8 - 5p = 2 - 3p
Move the terms
= -5p + 3p = 2-8
Collect like terms (calculate)
= -2p = -6
Divide both sides
p = 3 (Final Answer)
