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

I'll leave part 1 to you, I cannot draw here.
Part 2: substitution method
x = 2y
Substitute in the second eqn. and get
10y + 2y = 24
12y =24
y = 2
Substitute back into x and get
x = 4

Answer 2

Part 3: addition method
add the two equations and get
x + 5x + 2y - 2y = 24
6x = 24
x = 4
and proceed from here
