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.

Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect?

Help explain how to do this..

Answer 1

substitution
put 3x- 5 for y in the second equation

Answer 2

so it becomes
\(3x-5=6x-8\)

Answer 3

now you can solve for x
6x - 3x = 3x
8 + -5 = 3
3 = 3x
1= x

Answer 4

plug 1 for x in the first equation

Answer 5

3*1 = 3 - 5
y = -2

Answer 6

and when u graph them, the solution is (1,-2)

Answer 7

Thank you

Answer 8

your welcome

Answer 9

What would part b be?

Answer 10

at point (1,-2)

Answer 11

because the solution is (1,-2)

Answer 12

oh Thank you
