# Simultaneous eqns

## Re: Simultaneous eqns

Okay, I'm no sure, but I THINK that you treat the power of x-1 and 2y or whatever, as x and y, so just do the simultaneous equations normally.

Or, and I'm also not sure about this, reciprocal it?? And then multiply by the denominator to make it integers? I have no clue.

Ok here's a hint. Think of the numbers 3 and 2 how can you simply the equation so they contain these numbers!

## Re: Simultaneous eqns

Alright so i heres what i did.

I got both equations to have the same base numbers so i could deal with them, and i ended up with these new ones.

then i just used the indices rules to clean the equations up.

Then.. i don't know.

WAIIIT!

Did i get the second equation wrong.. if i get the 8 to be a 4..do i end up with this?

Yes? So now i can deal with

They have the same x values, but not the same base numbers..

URGH this is annoying.. am i on the right track?

Okay i understand everything going on. Rawnaq you just end up solving the powers simultaneously...

but i dont understand what you multiplied by 4 ....what did you multiply exactly to get your answer?

Lol, he multiplied by 4 to get rid of 4 as a denominator.
