2.8+2p\leq 16.8
Swap sides so that all variable terms are on the left hand side. This changes the sign direction.
2p\leq 16.8-2.8
Subtract 2.8 from both sides.
2p\leq 14
Subtract 2.8 from 16.8 to get 14.
p\leq \frac{14}{2}
Divide both sides by 2. Since 2 is positive, the inequality direction remains the same.
p\leq 7
Divide 14 by 2 to get 7.
