Homework Help: Solving Equations with variable on Both Sides

Posted by Mitch on Saturday, May 3, 2008 at 8:36pm.

I need help solving this. I've never been really good with fractions, so, thats probably why.:
3p/8 + 7p/16 - 3/4 = 1/4 + p/16 + 1/2

move all the ones with p to one side and the other fractions to the other so it becomes
3p/8 + 7p/16 - p/16 = 1/4 + 1/2 + 3/4

then change 3p/8 to 6p/16 by multiplying by 2 and 1/2 to 2/4 the same way.
6p/16 + 7p/16 - p/16 = 1/4 + 2/4 + 3/4

add both sides up
12p/16 = 6/4

isolate p
p = (6/4) x (16/12)
p = 2
