Answer:
Step-by-step explanation:
<u>This is the permutation of 4:</u>
- 4P4 = 4! = 1*2*3*4 = 24 ways
Fill in the y of the bottom equation with the top equation because it gives you what Y equals. To answer the question it would be easier to input the top equation into the bottom one. Once you then get the equation for X go to the equation on top and fill in the x to get the y. X=0 Y=2

Answer: x=8
Step-by-step explanation: Solve for x by simplifying both sides of the equation, then isolating the variable.
Hope this helps you out.
ANSWER
The smaller number is 7.
EXPLANATION
Let the numbers be x and y.
Then we have;
y-3x=3... eqn (1)
If the sum of the numbers is 3 then,
y+x=31... eqn (2)
Eqn(2) - Eqn (1)
x--3x=31-3
![4x = 28](https://tex.z-dn.net/?f=4x%20%3D%2028)
Divide both sides by 4,
![x = 7](https://tex.z-dn.net/?f=x%20%3D%207)
We put x=7 into the second equation,
y+7=31
y=31-7
y=24
The smaller of the two numbers is 7.
