3p+7 = 16+2p 3p-2p = 16-7 p = 9
4p+2 = 3p-7 4p-3p = -7-2 p = -9
3p+5+p = -23 3p+p = -23-5 4p = -28 p = -7

7 plus 3.4 equals 10.4

-14 + 3p = -9p - 21 add 14 and 9p to both sides, then 12p = -7 p = -7/12
3(4 plus 7) equals 33
5p-1=2p-20 3p=21 p=7
-2p+7.
-7 7b + 15 = (-34) 7b = (-34) - 15 7b =(-49) b = (-49) / 7 b= (-7)
3p + 18 = 5p + 4Subtract 4 from both sides3p + 14 = 5pSubtract 3p from both sides14 = 2pDivide both sides by 27 = pNote : For presentation purposes the unknown or variable is normally put as the subject of the equation. The answer is then presented as p = 7.
