Question

help

Answer 1

why don't you say what you think the answer is before i do it

Answer 2

x=0?

Answer 3

no

Answer 4

-54

Answer 5

I multiplied the top by 9

Answer 6

it looks suspiciously like both of those lines have the same slope

Answer 7

yes, good start

Answer 8

and got 54x-18y=45
so the 45 and -18y cancel

Answer 9

what do you get exactly when you add them up?

Answer 10

I got 108x=0

Answer 11

right
both the \(x\) terms and the \(y\) terms go
so on the left you have \(0\)

Answer 12

second one is \(-54x+18y=-45\)
when you add, the \(x\)'s add up to zero as well, not to \(108x\)

Answer 13

whoops I wrote it as positive

Answer 14

so if everything cancels then its all just 0?

Answer 15

i think that was your mistake
you should end up with \(0=0\) which means they are the same line

Answer 16

So that would mean there are infinite solutions?

Answer 17

if you bother to solve both of those equations for \(y\) you will see that you get the same thing
they are the same line
so yes, an infinite number of solutions

Answer 18

This is starting to make sense haha

Answer 19

good
