Answer:
p=3.8
Explanation:
collect like terms 3.8p+2.8p=6.6p
then add the numbers 8.4+6.18=14.58
move then variable to the left and change its sign(-3.2p now)
move the constant to the right and change its sign(-1.66 now)
your equation should be 6.6p-3.2p=14.58-1.66
collect like terms 6.6p-3.2p=3.4p
subtract the numbers 14.58-1.66=12.92
divide both sides of the equation by 3.4
p=3.8 is your final answer
