to solve this type of equation....get the P's to the same side
1) subtract 3 p's from each side 7p-12 -3p = 3p -3p
2) get new result 7p-3p -12 = 3p-3p
or 4p-12 = 0
3) get the p alone add 12 to each side 4p-12 +12 = 0 + 12
4) get new result 4p + 0 = 12
or 4p = 12
5) solve divide both sides by 4 4p / 4 = 12 / 4
or p = 3

add 12 to the other side of the equation
subtract 3p from 7p
divide 4 into 12
P=3

Add 12 to both sides to get:
7p = 3p +12
Subtract 3p from both sides to get:
4p = 12
Divide both sides by 4 to get:
p=3
You can check your work by substituting 3 for p in the original:
7(3) = 3(3) +12
21 = 9 +12....YES!

7p-12=3p
7p=3p+12 (subtract -12)
4p=12 (subtract 3p)
p=3 (divide by 4)

7p - 12 = 3
-7p -7p
-12 = -4p
-4 -4
3 =p
so p=3

7p-12=3p
4p=12
p=12/4=3

7p - 12 = 3p
1.) Subtract 7p from both sides.
Now you have: -12 = -4p
2.) Divide both sides by -4
Now you have: 3 = p
Therefore, the answer is, p = 3 .
