All the natural numbers which are not prime numbers are composite numbers as they can be divided by more than two numbers (1 and itself).
Example: factors of 12
12 ÷1 = 12
12÷ 2 = 6
12÷3= 4
12÷4 = 3
12÷6=2
12÷12 = 1
= {12,6,4,3,2,1}
Composite Number/ Its Factors
4 = {1,2,4}
6 = {1,2,3,6}
8 = {1,2,4,8}
9 = {1,3,9}
10 = {1,2,5,10}
12 = {1,2,3,4,6,12}
14 = {1,2,7,14}
15 = {1,3,5,15}
16 = {1,2,4,8,16}
18 = {1,2,3,6,9,18}
20 = {1,2,4,5,10,20}
21 = {1,3,7,21}
22 = {1,2,11,22}
24 = {1,2,3,4,6,8,12,24}
25 = {1,5, 25}
Hope it helps!

The solution for the system of linear equations 2x- y = 3 and y - x = 1 are x = 4 and y = 5
<h3>What are linear equations?</h3>
Linear equations are equations that have constant average rates of change, slope or gradient
<h3>How to determine the solution to the system?</h3>
A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
2x- y = 3
y - x = 1
Make y the subject in the second equation, by adding x to both sides of the equation
y - x + x = x + 1
This gives
y = x + 1
Substitute y = x + 1 in 2x- y = 3
2x- x - 1 = 3
Evaluate the like terms
x = 4
Substitute x = 4 in y = x + 1
y = 4 + 1
Evaluate
y = 5
Hence, the solution for the system of linear equations 2x- y = 3 and y - x = 1 are x = 4 and y = 5

Answer
a= -6
Step-by-step explanation:
-2(a-3)=12
1.) -2(a)= -2a
2) -2(-3)= 6
3) -2a+6=12
-6 -6
4) -2a/-2 = 12/-2
a = -6
Answer:
8
