Question

Make sure you read the directions for each part carefully. This system of equations will be used in all three parts of this question.
x-2y=0
5x+2y=24

Part 1: Solve the system by graphing. Draw the graphs on paper and indicate their intersection point. Type the ordered pair solution here as your answer to Part 1.

Part 2: Solve the system using the substitution method. Show all work here and indicate the solution for the system as an ordered pair.

Part 3: Solve the system using the addition method. Show all work here and indicate the solution for the system as an ordered pair.

Answer 1

x=2y
10y+2y=24
y=24/12=2
x=4
(4,2)

Answer 2

adding both, y is cancelled out
6x=24
x=4
y=2
(4,2)

Answer 4

that website doest help really

Answer 5

all it does is give u da answer but i need the explation to soooo

Answer 6

*explantion

Answer 7

graph cant be drawn over here. no whiteboard

Answer 8

u can draw both the lines by taking their intercepts

Answer 9

yea but the graph on that site is weird i dont get it

Answer 10

x-2y=0 is the first line, x=2y, passes through origin n (!,2), got it?

Answer 11

5x+2y=24
passes through (24/5,0) and(0,12)

Answer 12

join the points to get thelines, the point of intersection gives the solution
