5\times 2-4=-15p
Multiply both sides of the equation by 5.
10-4=-15p
Multiply 5 and 2 to get 10.
6=-15p
Subtract 4 from 10 to get 6.
-15p=6
Swap sides so that all variable terms are on the left hand side.
p=\frac{6}{-15}
Divide both sides by -15.
p=-\frac{2}{5}
Reduce the fraction \frac{6}{-15} to lowest terms by extracting and canceling out 3.
