-8p+5-12p=-4
Subtract 12p from both sides.
-20p+5=-4
Combine -8p and -12p to get -20p.
-20p=-4-5
Subtract 5 from both sides.
-20p=-9
Subtract 5 from -4 to get -9.
p=\frac{-9}{-20}
Divide both sides by -20.
p=\frac{9}{20}
Fraction \frac{-9}{-20} can be simplified to \frac{9}{20} by removing the negative sign from both the numerator and the denominator.
