4p-10=p+3p-2p ... simplify your equation by adding all the numbers with "p's" together )p+3p= 4p and 4p-2p = 2p)
4p-10=2p ....... subtract 4p from both sides
-10=2p-4p .... simplify
-10=-2p........ divide by -2 to isolate "p"
5=p

this is kind of the very beginning of equation algebra
you will need to know how to do this quickly and surely to be successful with the rest of math
remember, you can add and subtract things that are the same
you can add p and 2p and get 3p
you cannot add 2 (with no p) and 3p and get anything, you can't add them
you cannot add x and y and get anything, its just x+y, no simplifying
you can immediately combine all the p's on the right of the equation above yielding
4p-10=2p
then you can subtract 4p from each side to get all the p's together with each other and away from any non-p term, like "10" in this case
4p-4p-10=2p-4p
-10=-2p
finally we divide by -2 in order to get a single "p" by itself on one side of the equation, that is the goal, to see what one "p" is equal to
-10/-2=-2p/-2
5=p
horray, p=5
to check you can plug that value of 5 into every "p" in the original equation
4(5)-10=5+3(5)-2(5)
20-10=5+15-10
10=10
it checks, we are good

I assume you need to solve for p?...to do this you want to get all the p's on the same side of the equation...so you would have -10=p+3p-2p-4p...then you treat all the p's that are to the same exponent the same (so all the p's, and p^2's, etc)...since you only have p's you treat them as if they aren't in the way and just do the math with the constants in front of them...so you calculate :1+3-2-4=-2...this make the equation -10=-2p...now you divide the equation by the number in front of the variable (the p) in order to leave just p on one side of the equation...so -10/-2=p, or p=5!

4p-10=p+3p-2p
4p-10=4p-2p
4p-10=2p
-4p -4p
-10= -2p
-10/-2= 5
p=5

-10 = 4p - 2p -4p
-10 = 2p-4p
-10 = -2p
10 = 2p
p=5
