Combining Equations!

If
a = w(omega)^2 x r show that a = v^2 / r

my physics teacher said I will need to be able combine equations together but the thing is im so bad at that...
could someone show me how to do it with this example because I have no idea where to start.
Is there a way to combine equations together? Please help! :I

I am struggling to even interpret your equations, could you please type them out in a clearer way? (Perhaps using latex).

You know that v^2 / r = A
And you that a = w(omega)^2 x r

so v^2 / r = w(omega)^2 x r

then Cancel out the letters you can etc, im sure you can do the rest :smile:
