Question

A pair of equations is shown below:

y = 3x − 5
y = 6x − 8

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)

Answer 1

@rebeccaxhawaii @sloppycanada

Answer 2

well y = 3x-5 right we can set the first equation equal to the second one

Answer 3

3x-5 = 6x-8 then solve for x

Answer 4

@xo.msml

Answer 5

x=1

Answer 6

so plug that back into the first equation to find out what y is

Answer 7

-5

Answer 8

Answer 9

3(1)-5 = 3-5 = -2
6(1)-8 = 6-8 = ?

Answer 10

-2?

Answer 11

yes

Answer 12

what do i do next? I am really bad at this

Answer 13

that's actually the solution (1,-2)

Answer 14

that's the point where the graphs intersect.

Answer 15

oh wow thank you so much!!! Really appreciate it

Answer 16

will it be substitution or elimination

Answer 17

No problem

Answer 18

that's substitution
