Fundamental Theorem of Arithmetic states that every positive integer can be factor into a product of unique primes.
42=2*3*7
therefore all factors of 42 are all the combinations of the product
2, 3, 7, 6, 14, 21
and 1,42 in case you wanted to include them as well.

A conjecture and the paragraph proof used to prove the conjecture are shown.
Sveta_85 [38]

Angle 2 is equal to angle 3, by definition of angle bisector. In fact, a line is an angle bisector if it cuts the angle in two equal angles, which in this case are 2 and 3.

Finally, we can state that angles 1 and 3 are the same by the transitive property of congruence, because we prooved that angle 1 equals angle 2 and angle 2 equals angle 3, so we can conclude that angle 1 equals angle 3.

Hey there! :D

Add the expression's together. 

3x+y=27

-3x+4y= -42

3x+(-3x)= 0

y+4y=5y

27+(-42)= -15

5y=-15

Divide both sides by 5. 

y=-3

Now, find x.

3x+y=27

3x-3= 27

3x=30

x=10

The solution is (10,-3). 

I hope this helps!
