\frac{4+p}{-10}=-1
Multiply 5 and -2 to get -10.
\frac{-4-p}{10}=-1
Multiply both numerator and denominator by -1.
-\frac{2}{5}-\frac{1}{10}p=-1
Divide each term of -4-p by 10 to get -\frac{2}{5}-\frac{1}{10}p.
-\frac{1}{10}p=-1+\frac{2}{5}
Add \frac{2}{5} to both sides.
-\frac{1}{10}p=-\frac{5}{5}+\frac{2}{5}
Convert -1 to fraction -\frac{5}{5}.
-\frac{1}{10}p=\frac{-5+2}{5}
Since -\frac{5}{5} and \frac{2}{5} have the same denominator, add them by adding their numerators.
-\frac{1}{10}p=-\frac{3}{5}
Add -5 and 2 to get -3.
p=-\frac{3}{5}\left(-10\right)
Multiply both sides by -10, the reciprocal of -\frac{1}{10}.
p=\frac{-3\left(-10\right)}{5}
Express -\frac{3}{5}\left(-10\right) as a single fraction.
p=\frac{30}{5}
Multiply -3 and -10 to get 30.
p=6
Divide 30 by 5 to get 6.
