Problem:
%28p%2F3%29-%283p%2F8%29=5
We need common denominators to deduct one fraction from the other.
So we multiply the first fraction by 1 (same as 8/8), and the second fraction by 1 (same as 3/3).
%28p%2F3%29%288%2F8%29-%283p%2F8%29%283%2F3%29=5
Now we have the same denominators.
%288p%2F24%29-%289p%2F24%29=5
Now perform the deduction, we get:
%28-1p%29%2F24=5 ...same as... -%28p%2F24%29=5
Now multiply by -24 on both sides of the equation to determine the value of p.
p=5%2A%28-24%29
Result:
p=-125

p 3p
___ - ____ = 5
3 8
p/3-3p/8=5 find the common denominator for the fractions & combine them.
(8p-3*3p)/3*8=5
(8p-9p)/24=5 combine the p terms & cross multiply.
-p=5*24
-p=120
p=-120 ans.
Proof:
-120/3-3*-120/8=5
-40+360/8=5
-40+45=5
5=5
