Question 168189
P+7/2=-5/4
P=-5/4-7/2 [find a common denominator which is 4)
P=(-5-7*2)/4
P=(-5-14)/4
P=-19/4 ANS.
-----------------------------
Proof:
-19/4+7/2=-5/4
-19/4++14/4=-5/4
-5/4=-5/4

Thank you checkley77.  I really appreciate the break down that you gave me.  I just have one concern.  If the answer is -19/4 and you put that into the equation as -19/4+7/2 wouldn't that equal -12/6?  I am still a little confused.  The answer I got for P was -12/2 but I wasn't sure that I had the correct formula.
-12/2+7/2=-5/4
-5/2 does not = -5/4
I believe you are confused about the denominators of 2 & 4.
In order to combine these fractions they have to have the same denominator.
Hpe this helps.
