I think they are equal @gleaming geode

Nvm

Is the X mean multiply or it’s an variable

[gleaming geode]

var

I started by moving the x's to one side

[queen wigeon]

What grade is this?

[gleaming geode]

uhmm

im 15 yo

[queen wigeon]

So 11 or 10

[gleaming geode]

so grade 10 I think, in my country its a little different

[queen wigeon]

Yep

[gleaming geode]

So now I did this

and I have root of 5 - 5 on both sides

and I think that I can cancel them out somehow

I came up with this but im not sure if this is correct

[queen wigeon]

@slim tundra

[round herald]

you can always check by testing some values of x to verify

so test x=1, x=0, and x=2

[brisk path]

yeah

[brisk path]

would you put x <=

[round herald]

$\sqrt{5} - 5$ is negative and thus you need to flip the sign

uhh

[ebon ledge]

!𒐪 ɹɐupoɯ⇂ㄥ8𝟝 𒐪!

[round herald]

i think so?

[brisk path]

I dont think it would matter since ur dividing it on both sides

[round herald]

you can just do the double check method that should work

[brisk path]

you might be right hollup

since ur dividing by a negative number on both sides yeah

[gleaming geode]

hi, so this is correct?

yes, the sign flips 100% since im going over this at school right now

thats why im so sure

[brisk path]

Yeah the sign flips

[gleaming geode]

thanks
