Rearrange formula where subject appears twice

[djc123]

Hi guys

I have the following formula, but don't know how to make X the syubject.

(X/1.07 x 0.485) - (X x 0.3) - Y = Z

I got as fas as this (hardly impressive, I know):

(X/1.07 x 0.485) - (X x 0.3) = Z +Y


Is there a genius out there who can help me???

Thank you,

Danny

Now calculate:

0.485/1.07 = ?

The key idea will be to simplify the equation, combining like terms. (You can also think of this as factoring out the X.) Then X will only appear in one place, and the problem should look more familiar to you.

ex: 7x- .2x = 9
6.8x = 9
x=9/6.8 = ...
