Answer:

10/24 and 9/24

Step-by-step explanation:

24 is the common denominator because it is the next smallest number that both 12 and 8 go into. 12 x 2=24 but you have to do the same thing to the numerator if you do something to the denominator so since we multiplyed by 2 now multiply 5 by 2 and get 10. Then the same for 3/8 but 8 goes into 24 3 times so we miltiply by 3, 3x3=9 so you get 9/24 and 10/24. Hope this helps have a great day!

A) I included a graph, look below.

B)

Input the y in x = y + 3.

x = (-4x - 3) + 3
x = -4x + 0
Add 4x to both sides.
5x = 0
Divide both sides by 5.
x = 0

Input that x value in y = -4x - 3

y = -4(0) - 3
y = 0 - 3
y = -3

(0, -3)

C)

Convert both equations to Standard Form.

x = y + 3
Subtract y from both sides.
x - y = 3

y = -4x - 3
Add 4x to both sides.
4x + y = -3

Add the equations together.

4x + y = -3
x - y = 3
equals
5x = 0
Divide both sides by 5.
x = 0

Input that into one of the original equations.

0 = y + 3
Subtract 3 from both sides.
-3 = y

(0, -3)
