Apair of equations is shown below:

y = 8x − 9
y = 4x − 1

part a: explain how you will solve the pair of equations by substitution or elimination. show all the steps and write the solution. (5 points)

part b: if the two equations are graphed, at what point will the lines representing the two equations intersect? explain your answer. (5 points)

Let's solve this system of equation by substitution, alright?
A)
Step 1
Substitute "y= 4x-1"
[4x-1=8x-9}
Step 2
Isolate x for 4x-1 = 8x-9
• 4x-1 = 8x-9
Add 1 to both sides
• 4x-1+1 = 8x-9+1
Simplify
• 4x = 8x-8
Subtract 8x from both sides
• 4x-8x = 8x-8x-8
Simplify
• -4x = -8
Divide both sides by -4
• -4x/4 = -8/4
Simplify
• x = 2

For y = 4x-1
Substitute x=2
Therefore; y = 4(2)-1
                   y= 8-1
                   y= 7

Solution: x = 2, y = 7
B) The lines representing the two equations would intersect at (2,7). This is true because both coordinate points fulfill the equations shown above
