-\frac{1}{3}p-\frac{1}{3}\left(-3\right)-\frac{1}{4}\left(10-p\right)=0
Use the distributive property to multiply -\frac{1}{3} by p-3.
-\frac{1}{3}p+\frac{-\left(-3\right)}{3}-\frac{1}{4}\left(10-p\right)=0
Express -\frac{1}{3}\left(-3\right) as a single fraction.
-\frac{1}{3}p+\frac{3}{3}-\frac{1}{4}\left(10-p\right)=0
Multiply -1 and -3 to get 3.
-\frac{1}{3}p+1-\frac{1}{4}\left(10-p\right)=0
Divide 3 by 3 to get 1.
-\frac{1}{3}p+1-\frac{1}{4}\times 10-\frac{1}{4}\left(-1\right)p=0
Use the distributive property to multiply -\frac{1}{4} by 10-p.
-\frac{1}{3}p+1+\frac{-10}{4}-\frac{1}{4}\left(-1\right)p=0
Express -\frac{1}{4}\times 10 as a single fraction.
-\frac{1}{3}p+1-\frac{5}{2}-\frac{1}{4}\left(-1\right)p=0
Reduce the fraction \frac{-10}{4} to lowest terms by extracting and canceling out 2.
-\frac{1}{3}p+1-\frac{5}{2}+\frac{1}{4}p=0
Multiply -\frac{1}{4} and -1 to get \frac{1}{4}.
-\frac{1}{3}p+\frac{2}{2}-\frac{5}{2}+\frac{1}{4}p=0
Convert 1 to fraction \frac{2}{2}.
-\frac{1}{3}p+\frac{2-5}{2}+\frac{1}{4}p=0
Since \frac{2}{2} and \frac{5}{2} have the same denominator, subtract them by subtracting their numerators.
-\frac{1}{3}p-\frac{3}{2}+\frac{1}{4}p=0
Subtract 5 from 2 to get -3.
-\frac{1}{12}p-\frac{3}{2}=0
Combine -\frac{1}{3}p and \frac{1}{4}p to get -\frac{1}{12}p.
-\frac{1}{12}p=\frac{3}{2}
Add \frac{3}{2} to both sides. Anything plus zero gives itself.
p=\frac{3}{2}\left(-12\right)
Multiply both sides by -12, the reciprocal of -\frac{1}{12}.
p=\frac{3\left(-12\right)}{2}
Express \frac{3}{2}\left(-12\right) as a single fraction.
p=\frac{-36}{2}
Multiply 3 and -12 to get -36.
p=-18
Divide -36 by 2 to get -18.
