You need to get the Ps on one side together.
9p-2p = 60-4
7p = 56
p = 8

9 p+ 4 = 2p + 60
get p on one side
9p + 4 = 2p + 60
-2p -2p
Twos cancel out
9-2 = 7
7p + 4 = 60
combine like terms
7p + 4 = 60
7p - 4 = 60 - 4
7p=56
isolate the variable to solve for p
p = 56 \7
p=8

p = 8
9 x 8 = 72 + 4 = 76
2 x 8 = 16 + 60= 76

9p + 4 = 2p + 60
9p - 2p + 4 = 60
9p -2p = 60 - 4
7p = 56
p = 8

Get the p's on one side and the numbers on the other.
9p + 4 = 2p + 60
9p = 2p + 60 - 4
9p = 2p + 56
9p - 2p = 56
7p = 56
p = 56 / 7
p = 8

9p+4=2p+60
9p - 2p = 60 - 4
7p = 56
p = 8

Simple equation.
9p-2p=60-4... take the +4 from the left to the right,changing the value to -4, and similarly take the +2p from the right to the left,again changing the sign from +2p to -2p
7p=56
p=8

looks like we're doing ALL your maths homework here. Remember whatever you do to one side of the equation you must do to the other. So........to get all the p's on one side subtract 2p from both sides. ......9p+4 -2p=60 then to get all the numric values together subtract (in this case 4) from both sides
......9p - 2p = 60 - 4
7p= 56
p= 8
