3p+5+p = -23 3p+p = -23-5 4p = -28 p = -7
-9p + 6p = -3p
3p = 2p + 12subtracting 2p from both sidesp = 12 ■
First get all the p variables on one side of the equation by subtracting 6p from both sides. Giving you 3p + 14 = 23 Now subtract 14 from both sides. 3p = 9 Finally divide both sides by 3. p = 3
p = -1
3p plus 7 equals 34, where P is equivalent to number 9.
3p+7 = 16+2p 3p-2p = 16-7 p = 9
3p+5+p = -23 3p+p = -23-5 4p = -28 p = -7
-9p + 6p = -3p
4p+2 = 3p-7 4p-3p = -7-2 p = -9
3p = 2p + 12subtracting 2p from both sidesp = 12 ■
First get all the p variables on one side of the equation by subtracting 6p from both sides. Giving you 3p + 14 = 23 Now subtract 14 from both sides. 3p = 9 Finally divide both sides by 3. p = 3
p = -1
13 + 3p = -2subtract 13 from each side, 3p = -15divide each side by 3, p = -5
p+2 = 2-3p p+3p = 2-2 4p = 0 p = 0
16p + 6q - 3p - 8q = (16p - 3p) + (6q - 8q) = 13p -2q
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.
