Question

x+5y=8
-2x-10y=4

Answer 1

what methods have you learned so far so solving system of equations?

Answer 2

-2(x+5y=8) --> -2x-10y=-16
-2x-10y=4 --> -2x-10y=4
Graphing, substitution, and addition.

Answer 3

great which one do you want to try out?

Answer 4

I tried addition

Answer 5

-2x-10y=-16
-2x-10y=4


0+0=20


Wow this doesnt look right.

0 can not equal 20 so this means there is no solution to the system of equations

Answer 6

I tried addition to show that the first part could mirror the second part but equal a different number

Answer 7

It's multiple choice and I'm really confused by it.
x = 3, y = 1
x = -2, y = 0
The lines are parallel.
The lines coincide.

Answer 8

Where do you need help @Romero

Answer 9

Oh Ok I got it. I said there is no solution and by that I mean when you graph both of the lines...they will never cross each other....can you tell me what lines never cross each other?

Answer 10

Parallel xD

Answer 11

yes!!

Answer 12

Thanks

Answer 13

good job!

Answer 14

They are parallel but not coinciding..
