I am looking to make x the subject so x= (something)

so you subtracted x from both sides to give 7 - x = 3? - April 22nd 2010, 11:17 AMMikeysharkface

I could figure it out if it was a simple equation like that because the answer is obviously 4. But the questionvwhich i have to answer says:

Make x the subject of the formula 7 = 3 + x - April 22nd 2010, 11:18 AMmelvis

If I subtracted 3 from 7 = 3 + x it would leave me with x = 4

it can't be that easy, surely - April 22nd 2010, 12:02 PMundefined
