-29.5+0.1p-0.9p=5.3
Subtract 0.9p from both sides.
-29.5-0.8p=5.3
Combine 0.1p and -0.9p to get -0.8p.
-0.8p=5.3+29.5
Add 29.5 to both sides.
-0.8p=34.8
Add 5.3 and 29.5 to get 34.8.
p=\frac{34.8}{-0.8}
Divide both sides by -0.8.
p=\frac{348}{-8}
Expand \frac{34.8}{-0.8} by multiplying both numerator and the denominator by 10.
p=-\frac{87}{2}
Reduce the fraction \frac{348}{-8} to lowest terms by extracting and canceling out 4.
